edit : I ended up upgrading to macOS Catalina yesterday and replacing bash with zsh. One thing that should be noted is that the stackcommand worked previously, but despite all the tinkering not ghci
After deleting all the files that had anything to do with Haskell, I retried running curl --proto '=https' --tlsv1.2 -sSf https://get-ghcup.haskell.org | sh
This second time there was an error with the command line tools so I had to install them manually with xcode-select --install. After rerunning the curl, I added the path to the environmental file to my zsh profile manually with :
. "$HOME/.ghcup/env"\
echo '. $HOME/.ghcup/env' >> "$HOME/.zshrc"
Here is the content of the env file :export PATH="$HOME/.cabal/bin:/Users/agnel/.ghcup/bin:$PATH"
Now everything seems to be working (I never reinstalled stack, but I think I might leave that to the side while I learn the basics of the language).
I installed the Haskell Platform yesterday but am having a hard time getting it to work correctly.
The firsts steps I did are:
curl -sSL https://get.haskellstack.org/ | sh
curl --proto '=https' --tlsv1.2 -sSf https://get-ghcup.haskell.org | sh
On step 1. the instructions said to append /Users/.../.local/bin the PATH variable (which I did in /etc/paths. On step 2, the script was supposed to pop up a dialog box (and didn't) when installing the necessary command line tools. It also said to rerun the script once complete (which I did). The script also said I should adjust my PATH variable, and source /Users/.../.ghcup/env in my shell configuration. It asked to this automatically but failed having not found the ~/.bashrc File. (I read that on Mac in contrary to linux, only .bash_profile is loaded upon opening of a terminal window so I adjusted the path variable there manually. I've spent forever messing around with the path variables and every time I try and run "$ ghci" I get the same -bash: ghci: command not found error message. If anyone has a solution to this problem I would be very grateful for an answer. If not, could someone with a working distribution of Haskell on their computer show me what their path variables look like?
Thanks!
A simple solution would just be to restart your terminal and you are good to go.
After installing the Haskell platform for the first time on a new mac with Catalina, I also got
~> ghci
zsh: command not found: ghci
What worked in my case was to use, instead of the plain ghci,
stack ghci
To get back the familiar behaviour, I created in my homedirectory a file named .zshrc containing
alias ghci='stack ghci'
If you open a new terminal, this file will automatically be executed.
I'd be interested to know if there is another solution.
Check if the ghcup command is working or not.
If not, make sure the .zshrc file has command for execution of ghcup. It should look something like this -
[ -f "/Users/myusername/.ghcup/env" ] && source "/Users/myusername/.ghcup/env" # ghcup-env
If the file exists, simply restarting terminal will work.
If it is still not working, set GHC as default using ghcup - follow this
I installed vscode today and followed the steps on tutorials on youtube to set up. My terminal started to act weird after I called python through the terminal and tried to use pip install command but failed. I uninstalled the app, deleted all the relevant files, and tried to reopen the terminal. The terminal still has the same warnings.
I have contacted Apple Tech support and they say my terminal got modified by the app. They asked me to contact the app developer.
I don't know what I did to get where I am now. I would appreciate any help that can bring my terminal back to normal.
Below are the warnings even after I uninstalled the app:

Check your shell's startup script, it looks like you have text there that aren't shell commands. I don't know whether you have bash or zsh as your shell, but check all of these files just to be sure:
~/.bashrc
~/.bash_aliases
~/.bash_profile
~/.bash_login
~/.zshrc
~/.zshenv
~/.zprofile
~/.zlogin
~/.profile
Also look into any files that are sourced by these files.
I simply want to run an executable from the command line, ./arm-mingw32ce-g++, but then I get the error message,
bash: ./arm-mingw32ce-g++: No such file or directory
I'm running Ubuntu Linux 10.10. ls -l lists
-rwxr-xr-x 1 root root 433308 2010-10-16 21:32 arm-mingw32ce-g++
Using sudo (sudo ./arm-mingw32ce-g++) gives
sudo: unable to execute ./arm-mingw32ce-g++: No such file or directory
I have no idea why the OS can't even see the file when it's there. Any thoughts?
This error can mean that ./arm-mingw32ce-g++ doesn't exist (but it does), or that it exists and is a dynamically linked executable recognized by the kernel but whose dynamic loader is not available. You can see what dynamic loader is required by running ldd /arm-mingw32ce-g++; anything marked not found is the dynamic loader or a library that you need to install.
If you're trying to run a 32-bit binary on an amd64 installation:
Up to Ubuntu 11.04, install the package ia32-libs.
On Ubuntu 11.10, install ia32-libs-multiarch.
Starting with 12.04, install ia32-libs-multiarch, or select a reasonable set of :i386 packages in addition to the :amd64 packages.
I faced this error when I was trying to build Selenium source on Ubuntu. The simple shell script with correct shebang was not able to run even after I had all pre-requisites covered.
file file-name # helped me in understanding that CRLF ending were present in the file.
I opened the file in Vim and I could see that just because I once edited this file on a Windows machine, it was in DOS format. I converted the file to Unix format with below command:
dos2unix filename # actually helped me and things were fine.
I hope that we should take care whenever we edit files across platforms we should take care for the file formats as well.
This error may also occur if trying to run a script and the shebang is misspelled. Make sure it reads #!/bin/sh, #!/bin/bash, or whichever interpreter you're using.
I had the same error message when trying to run a Python script -- this was not #Warpspace's intended use case (see other comments), but this was among the top hits to my search, so maybe somebody will find it useful.
In my case it was the DOS line endings (\r\n instead of \n) that the shebang line (#!/usr/bin/env python) would trip over. A simple dos2unix myfile.py fixed it.
I found my solution for my Ubuntu 18 here.
sudo dpkg --add-architecture i386
Then:
sudo apt-get update
sudo apt-get install libc6:i386 libncurses5:i386 libstdc++6:i386
I got this error “No such file or directory” but it exists because my file was created in Windows and I tried to run it on Ubuntu and the file contained invalid 15\r where ever a new line was there.
I just created a new file truncating unwanted stuff
sleep: invalid time interval ‘15\r’
Try 'sleep --help' for more information.

As mentioned by others, this is because the loader can't be found, not your executable file. Unfortunately the message is not clear enough.
You can fix it by changing the loader that your executable uses, see my thorough answer in this other question: Multiple glibc libraries on a single host
Basically you have to find which loader it's trying to use:
$ readelf -l arm-mingw32ce-g++ | grep interpreter
[Requesting program interpreter: /lib/ld-linux.so.2]
Then find the right path for an equivalent loader, and change your executable to use the loader from the path that it really is:
$ ./patchelf --set-interpreter /path/to/newglibc/ld-linux.so.2 arm-mingw32ce-g++
You will probably need to set the path of the includes too, you will know if you want it or not after you try to run it. See all the details in that other thread.
I got the same error for a simple bash script that wouldn't have 32/64-bit issues. This is possibly because the script you are trying to run has an error in it. This ubuntu forum post indicates that with normal script files you can add sh in front and you might get some debug output from it. e.g.
$ sudo sh arm-mingw32ce-g++
and see if you get any output.
In my case the actual problem was that the file that I was trying to execute was in Windows format rather than Linux.
Below command worked on 16.4 Ubuntu
This issue comes when your .sh file is corrupt or not formatted as per unix protocols.
dos2unix converts the .sh file to Unix format!
sudo apt-get install dos2unix -y
dos2unix test.sh
sudo chmod u+x test.sh
sudo ./test.sh
I had the same problem with a file that I've created on my mac.
If I try to run it in a shell with ./filename I got the file not found error message.
I think that something was wrong with the file.
what I've done:
open a ssh session to the server
cat filename
copy the output to the clipboard
rm filename
touch filename
vi filename
i for insert mode
paste the content from the clipboard
ESC to end insert mode
:wq!
This worked for me.
Added here for future reference (for users who might fall into the same case):
This error happens when working on Windows (which introduces extra characters because of different line separator than Linux system) and trying to run this script (with extra characters inserted) in Linux. The error message is misleading.
In Windows, the line separator is CRLF (\r\n) whereas in linux it is LF (\n). This can be usually be chosen in text editor.
In my case, this happened due to working on Windows and uploading to Unix server for execution.
I just had this issue in mingw32 bash. I had execuded node/npm from Program Files (x86)\nodejs and then moved them into disabled directory (essentially removing them from path). I also had Program Files\nodejs (ie. 64bit version) in path, but only after the x86 version. After restarting the bash shell, the 64bit version of npm could be found. node worked correctly all the time (checked with node -v that changed when x86 version was moved).
I think bash -r would've worked instead of restarting bash: https://unix.stackexchange.com/a/5610
I had this issue and the reason was EOL in some editors such as Notepad++. You can check it in Edit menu/EOL conversion. Unix(LF) should be selected.
I hope it would be useful.
Hit this error trying to run terraform/terragrunt (Single go binary).
Using which terragrunt to find where executable was, got strange error when running it in local dir or with full path
bash: ./terragrunt: No such file or directory
Problem was that there was two installations of terragrunt, used brew uninstall terragrunt to remove one fixed it.
After removing the one, which terragrunt showed the new path /usr/bin/terragrunt everything worked fine.
For those encountering this error when running a java program, it's possible that you're trying to run a 64-bit java program using on a 32-bit linux operating system.
I only realised when I ran ldd on 64-bit java which reported:
ldd /usr/java/jdk1.8.0_05/bin/java
'not a dynamic executable'
Whereas the old 32 bit java reported sensible results:
ldd /usr/java/jdk1.8.0_05/bin/java
In my case, it turns out the file was a symlink:
$ cat deluge-gtk.lock
cat: deluge-gtk.lock: No such file or directory
$ file deluge-gtk.lock
deluge-gtk.lock: broken symbolic link to 32309
Misleading errors like this are fairly common on Linux. Related discussion: https://lwn.net/Articles/532771/
Give it a try by changing the name of file or folder which is not showing in terminal/command prompt.
step1 : change the name of file or folder.
step2 : cd filename/foldername
For future readers, I had this issue when trying to launch a Django server using gunicorn. I was using AWS CodeBuild to build the virtual environment and run tests and using CodeDeploy to put the built artifacts onto the production server and launch the new version (all environments were Ubuntu 20.04). I had mistakenly thought that env/bin/... contained actual binaries of native libraries but that was not the case. It was just Python scripts with a shebang of the path to the Python interpreter on the build machine. In my case, the machine installing the packages and actually running the packages was different. To be more specific, all of the files in env/bin had the shebang #!/codebuild/output/src715682316/src/env/bin/python, so of course running env/bin/gunicorn on the production server would fail. The cryptic error message was when Ubuntu would tell me that env/bin/gunicorn didn't exist as opposed to saying /codebuild/output/src715682316/src/env/bin/python didn't exist. I was able to fix this problem by starting gunicorn using python3 env/bin/gunicorn instead of env/bin/gunicorn.
In a .sh script, each line MUST end with a single character - newline (LF or "\n").
Don't make mistakes like me, because my text-editor of choice is Notepad++ in Win.
Whenever I start up Terminal on my Macbook Air, I get this message:
-bash: ≈: command not found
How do I fix this error? I'm running Mavericks version 10.9.4 if that helps at all.
EDIT: Fixed this error by using the bash -x method, found out it was a random '≈' character left in ~/.profile that needed to be deleted. Thanks for the answers :)
To debug you can try this:
bash -x -l
(the -l might not be needed).
I definitely agree with Barmar, there is something in your bash startup scripts.
There is not a great way to do this, but here is the protocol to remedy it.
Confirm it is your bash profile by first killing the process with a control + C if it is hung. Then do a source ~/.bash_profile and see if you get that same error.
Backup your bash profile cp ~/.bash_profile bashprofile.txt
Then comment out part of your bash profile. With text wrangler you can do a command + slash.
Save, then do a source ~/.bash_profile and see if the error still prints.
Repeat with different areas of the script until you have isolated the infected region.
