I am trying to add Racket's bin to my list of environment/path variables.
Here is the location of Racket's bin folder:
/Applications/Racket/bin
Here is what I have added to my .bash_profile file:
export PATH=$PATH:/Applications/Racket/bin
Here is the Path output from set:
PATH=/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/Applications/Racket/bin
However, when I run ./racket, I still get:
-bash: ./racket: No such file or directory
I am able to run ./racket from Racket's bin directory (meaning that it probably isn't a 32- v 64-bit issue).
However, when I run ./racket, I still get a "-bash: ./racket: No such
file or directory"
Run it like this instead:
racket
When you run ./racket it means run an executable racket from your current directory.

I am trying to permanently add a binary to the path variable on mac os. I have read several posts and blogs, it just does not work.
The question: given a directory /dir which contains an executable foo, how can I make it such that I can execute foo in the commandline without having to type export PATH... etc., and without having to move the foo executable to the bin folder?
I know there exists several scripts that are run on startup and whenever you open a command prompt, I just cannot seem to find the correct one. If I manually execute the export PATH... command and then do foo, it works.
If the export command works for you, just add it to either ~/.zshrc (on zsh) or ~/.bashrc (on bash).
I have downloaded javacc-5.0 and tried to follow various different guides to no avail.
I unzipped the package, modified the PATH variable to contain ../javacc-5.0/bin/lib/javacc.jar directory and ensured that all the correct files are executable. However, a which javacc command gives no output and trying to run the javacc exec has also given the error Could not find or load main class javacc (the jar file is definitely there in the lib directory).
In the ...../javacc-5.0/bin directory, there should be a file called javacc that should looks something like this
#!/bin/sh
JAR="`dirname $0`/lib/javacc.jar"
case "`uname`" in
CYGWIN*) JAR="`cygpath --windows -- "$JAR"`" ;;
esac
java -classpath "$JAR" javacc "$#"
If so, edit your PATH variable to include /....../javacc-5.0/bin, i.e. the absolute path of that bin directory. There is no need for the PATH variable to include /....../javacc-5.0/bin/lib/javacc.jar; so take that out.
Start a new terminal. In the new terminal, check the PATH variable with echo $PATH. Try which javacc. Try javacc.
javacc can easily be installed using Homebrew:
brew install javacc

I just installed CD-HIT and followed these instructions:
Installation
Most CD-HIT programs were written in C++. Installing CD-HIT package is very simple:
download current CD-HIT at http://bioinformatics.org/cd-hit, for example cd-hit-2006-0215.tar.gz
unpack the file with ” tar xvf cd-hit-2006-0215.tar.gz --gunzip”
change dir by “cd cd-hit-2006”
compile the programs by “make”
you will have all cd-hit programs compiled
I followed these steps and indeed .exe files were made:
cdhit.c++ cdhit-est-2d.c++ clstr_select_rep.pl
cd-hit.exe cd-hit-est-2d.exe clstr_size_histogram.pl
cdhit.o cdhit-est-2d.o clstr_size_stat.pl
cdhit-2d.c++ cd-hit-para.pl clstr_sort_by.pl
cd-hit-2d.exe cdhit-utility.c++ clstr_sort_prot_by.pl
cdhit-2d.o cdhit-utility.h clstr_sql_tbl.pl
cd-hit-2d-para.pl cdhit-utility.o clstr_sql_tbl_sort.pl
cdhit-454.c++ ChangeLog clstr2tree.pl
cd-hit-454.exe clstr_cut.pl clstr2txt.pl
cdhit-454.o clstr_list.pl clstr2xml.pl
cd-hit-auxtools clstr_list_sort.pl doc
cdhit-common.c++ clstr_merge.pl FET.pl
cdhit-common.h clstr_merge_noorder.pl license.txt
cdhit-common.o clstr_quality_eval.pl make_multi_seq.pl
cdhit-div.c++ clstr_quality_eval_by_link.pl Makefile
cd-hit-div.exe clstr_reduce.pl plot_2d.pl
cdhit-div.o clstr_renumber.pl plot_len1.pl
cd-hit-div.pl clstr_rep.pl psi-cd-hit
cdhit-est.c++ clstr_reps_faa_rev.pl README
cd-hit-est.exe clstr_rev.pl usecases
cdhit-est.o clstr_select.pl
However when I typ: cd-hit-est in the cygwin command line, it will say: -bash: cd-hit.exe: command not found. I'm not able to figure out why this is happening. Even when I'm in the folder were the .exe files are located it still will give the same error.
When you try to run command without a path, bash tries to find the command name in each directory from the PATH environment variable.
Usually current directory "." is not in the PATH so you have to run command adding absolute or relative path before command name:
./cd-hit.exe
or
/absolute/path/to/your/cd-hit/program/cd-hit.exe
If you want to permanently run command cd-hit.exe from anywhere, just add the directory where cd-hit was compiled to any existing auto-loaded bash profile files:
.profile
.bashrc
.bash_profile
like
PATH=$PATH:/absolute/path/to/your/cd-hit/program
export PATH
I just made a .c file and compiled it with gcc in the terminal on OS X 10.8.2.
My syntax was gcc -o <filename> <sourcefile> and that was fine. Now I see I have an executable and file <filename> tells me as such, but I'm not sure how to actually run it beside double clicking the icon, /lame. When I try running the executable by just typing I get command not found, but I thought it was executable...?
Thank you.
EDIT: I"m so stupid, it was just open <filename>
Unix will only run commands if they are available on the system path, as you can view by the $PATH variable
echo $PATH
Executables located in directories that are not on the path cannot be run unless you specify their full location. So in your case, assuming the executable is in the current directory you are working with, then you can execute it as such
./my-exec
Where my-exec is the name of your program.
To run an executable in mac
1). Move to the path of the file:
cd/PATH_OF_THE_FILE
2). Run the following command to set the file's executable bit using the chmod command:
chmod +x ./NAME_OF_THE_FILE
3). Run the following command to execute the file:
./NAME_OF_THE_FILE
Once you have run these commands, going ahead you just have to run command 3, while in the files path.
I am on Mac's OS 10.6, and I am trying to learn a thing or two about shell scripting. I understand how to save a shell script and make it executable, but I am wondering what I can do or where I can save the file to make it global (that is, accessible no matter what folder I am in).
For example, if I save a .sh file in the /Users/username/ directory and make it executable, I can only execute that script in that specific directory. If I navigate to /Users/username/Downloads, for example, I can't execute the script.
Also, any suggestions of resources for learning more about shell scripting would be helpful. Thanks
/usr/local/bin would be the most appropriate location. Mac OS X has it in the PATH by default
There are two ways to do it -
Put your script in usr/local/bin and make sure it is executable(chmod +x my_script)(This is already set in the path, you can check by doing an echo $PATH)
Create a folder in your home directory called bin. (For your personal scripts)
cd ~ (Takes you to your home directory)
mkdir bin (create a bin folder)
vim .bash_profile (to set path environment variable)
export PATH=~/bin:$PATH (Press i then add this line and then do esc and type :wq)
Now you can just type the name of your script and run it from anywhere you want.
** NOTE: If you want to run the script with a shortened command rather than typing your entire filename, add the following to your .bash_profile:
alias myscript='my_script.sh'
Then you can run the script by simply typing myscript. (you can sub in whatever alias you'd like)
Traditionally, such scripts either go in ~/bin (ie: the bin directory in your home directory) or /usr/local/bin/ The former means the script will only work for you, the latter is for scripts you want anybody on the system to be able to run.
If you put it in ~/bin, you may need to add that to your PATH environment variable. /usr/local/bin should already be on the path.
In mac operating system
Open bash ~/.bashrc file.
add path of your script in your bashrc file , using
export PATH="$PATH:/Users/sher.mohammad/Office/practice/practiceShell"
Open your ~./bash_profile file and add [[ -s ~/.bashrc ]] && source ~/.bashrc
open new terminal window
Now whenever you will open your terminal your script will be loaded
This one is super easy if you are familiar with your bashrc file! This will entirely use just your .bashrc file and takes 2 seconds to accomplish.
(I use Arch Linux Manjaro so I use .bashrc located in my home directory)
The code to be placed in your .bashrc file:
# Simple bashrc method to launch anything in terminal from any directory
YOURCOMMAND () {
cd /path/to/directory/containing/your/script/ && ./YOURSCRIPT
}
As you can see, first you use the simple 'cd' command and give it the directory of the scripts location, then use '&&' so that you can make the next command executed right after, and finally open your script just as you would normally! Super easy and saved right in your .bash file! :)
Hope I've helped someone!
Sincerely,

On using bash shell, write that script as function and then put it to the .bashrc or source the file which containing that function by "source file_name"
Now execute the script by function call in the shell.
Either saving it in /usr/bin (or any other directory present in PATH) or editing PATH to include the directory you saved it in will basically make it run in any directory.
from the working directory of 'script.sh'" mv [script.sh] /usr/local/bin"( not tested but seems to be the least complex way IMO.)
You should put it in the global executable directory on your machine. I think that would usually be /usr/bin on Unix-based operating systems (this would however most often require super user privileges on that machine).
You could also put it in any other directory that is in the $PATH environment variable, although it would only work for those users who have that directory in that variable.
You can find the value of $PATH by typing echo $PATH in a shell. The directories are separated by :.
