This question might be silly, and I think it is something so basic that I can't even find the solution because it might be obvious to everyone.
Here's the thing:
I want to download a file from mega.nz using bash.
I found this bash script on github: https://github.com/tonikelope/megadown/blob/master/megadown
I don´t know how to run this
Tried:
Copy-pasting the file to a file called "megadown.sh" and then running:
$ bash megadown.sh 'https://mega.nz/#F!BwQy2IAS!AwWpbCPzgLf_5jyj76q7qw'
this returns:
Reading link metadata...
Oooops, something went bad. EXIT CODE (3)
Which tells me that at least the code is running, but I don't know if I am doing it correctly.
This is better than my previous attempt $ megadown 'URL' (as the documentation suggested), which resulted in "command not found"
First, make sure you have installed the dependencies:
sudo apt-get install openssl curl pv jq
Then try running this command:
bash megadown.sh -o FILE_NAME "LINK"
It will download the file specified by the URL to a file called FILE_NAME.

I've been trying to create a bash script that allows me to transfer my existing dev setup to a brand new macbook.
I set up a bash script which is supposed to automate this process but for some reason when I call the script using curl, it doesnt seem to reliably run the whole thing and I cant figure out why that is. example of commands being printed to the console and note executed
If I were to manually enter each line into the terminal and execute, things work as expected however doing so defeats the purpose of the script.
I'll attach some screenshots of the terminal output so you can see the exact issues I'm facing and at which point it behaves oddly.
I've had to run the script a few times to get it to execute the skipped steps but it would be good to understand why certain steps are getting missed. Here's a link to my gist containing the script. Would appreciate any suggestions for improvements or explantations for the behaviour I'm seeing.
Things I have tried that havent resolved my issue:
Splitting the script into two smaller scripts
Erasing my mac and running the script again (done this several times)
Adding sleep 5 between each command
edit: this is how I'm running the script
sudo curl -Lks https://gist.githubusercontent.com/curtis-j-campbell/b695513a44393c3a5084c011c6d0c890/raw | /bin/bash
Thanks in advance
It appears that everything after brew install git is being echoed. That suggests that something in that command is copying its stdin to stdout, so it's processing the rest of the script. Change that line to
brew install git </dev/null
so it won't read the script as its stdin.
Also, you don't need to run curl under sudo. If you need privileges to install the program, you should run bash as the superuser, not curl.
curl -Lks https://gist.githubusercontent.com/curtis-j-campbell/b695513a44393c3a5084c011c6d0c890/raw | sudo /bin/bash
I'm both new here and with MacOS and coding.
I know in windows I can create bash file to have an executable command in cmd. I've researched and discovered I can use similar file with MacOS (shell files) but I'm struggling to understand how to make one. I've tried different route:
As first thing I've tried creating a file in txt editor with this code:
#!/bin/bash
pip3 install pgzero
echo Installing Pygame Zero
Using later 'chmod 700 Filename' in terminal. It did not worked
I then tried with Apple Scrip, with a code like:
tell application "Terminal"
activate
do script "pip3 install pgzero"
do script "echo Installing Pygame Zero"
end tell
and it kinda worked, but it wasn't an executable
Then I tried with another approach found on google:
echo '#!/bin/bash
pip3 install pgzero
echo Installing PyGame Zero'> ~/Desktop/PygameInstaller.command
chmod 740> ~/Desktop/PygameInstaller.command
and it still didn't worked D:
Can someone land a bit of help? I'm starting feeling lost q,q
Thank you in advance!
In terms of what you want in your shell script, your first attempt is probably close to what you want but the echo should precede the pip3 command. I guess if you change the verb from Installing to Installed, then you could leave it where it is.
$ cat <<EOF > ~/Desktop/PygameInstaller.command
#!/bin/bash
echo Installing Pygame Zero
pip3 install pgzero
EOF
$ chmod 700 ~/Desktop/PygameInstaller.command
The permissions you assign to the script and the script's location depend on who you want to grant execution. If it's only you, then your desktop and 700 should be fine.
Now, if you want to execute the script from a command line like what you would see if you opened an instance of Terminal.app, then you have options.
If you want to fully specify the command, then you would type this (showing prompt which you would not type):
$ ~/Desktop/PygameInstaller.command
If you want to specify only the name of the script, then you would type this after adding ~/Desktop to your PATH:
$ PATH="$HOME/Desktop:$PATH"
$ PygameInstaller.command
If you prefer to type only PygameInstaller, then don't put the code in a file named PygameInstaller.command. Instead, you put the code in a file called simply PygameInstaller.
If you need the script to be executable by everyone, then put it in /usr/local/bin because most people will either have that in their PATH or have no political problem doing so. But you'll have to use the sudo command to elevate your privileges to accomplish that task.
If, however, you want to have that script be treated like any other app that you can launch with a double-click, then you have significantly more work to do.
Been pulling out my hairs on this one, it must be so simple but for some reason I can't get it to work..
I'm using go1.15, on Ubuntu 18.04, trying to build lnd from source off of github.
I run sudo make install after all the preliminaries but keep getting error

go version returns normally
I'm an intermediate programmer, but been using Linux for many years and do not understand what is going on.
Just in case somebody finds this the answer is that the golang installation instructions say to update your PATH variable in ~/.profile but this only applies to interactive shells, not scripts. So if you want to properly update this for scripts you'll have to find another way. My quick fix was just inserting a PATH update into the script itself.
Link for solution is:
Bash script can't execute Go command
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'm trying to run a CLI tool in Linux (Mint) which allows me to edit subtitles. It is named subedit: github link. In order to run it, I've added executable permission with chmod +x and added it to the path in bash. However, when I run it, I get the following error message:
bash: /home/main/Documents/shellTools/subedit/subedit: /usr/bin/bash: bad interpreter: No such file or directory
I'm not very experienced with external bash programs and forgot to do something that would be obvious in hindsight.
When I do echo $PATH this is the output:
/home/main/.local/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/home/main/Documents/shellTools/subedit/
Could somebody please help?
Assuming bash is installed, (it usually is), change the first line of subedit from:
#!/usr/bin/bash
to:
#!/bin/bash
Or if one would prefer not to edit subedit, try this one-liner covering what Al-waleed Shihadeh suggested:
ln -s "$(which bash)" /usr/bin/bash
It seems that you don't have bash installed, you can verify that by running
which bash
if the above command returns "bash not found", then you need to install it.
In case the above command returns a path, you can use the below command to add a symlink to the expected path
ln -s $(path from the above command) /usr/bin/bash
Use the command termux-chroot ONCE!
If you want to always run at the start of a session, be sure to check if it was never run before.
if [ -z $CHROOT ]; then
CHROOT=1
termux-chroot
