What I basically want to achieve is to type in a custom command in the terminal and a specific shell script should run each time.

I could achieve the above requirement with folders,by modifying the bashrc file like below

alias myScripts="cd /home/arun/Desktop/scripts"

Now when I try to do the same with a bash script by modiying the bashrc file as given below,

alias masterScript="bash /home/arun/Desktop/scripts/myMasterScript.sh"

now when I type masterScript im getting the following error:

"bash : No such file or directory" error

How can I correct this?

  • I think i may have an answer but let me make sure I have this correct .. when you ... alias myScripts in bashrc it will open the folder path but if you alias it to a script it says no file... is this right?

    I do not understand why this would be preferable to just put your script in your $PATH. If you move your script to ~/bin and add ~/bin to your path variable you can execute it from everywhere.

  • Or if you don't want to change $PATH linking the script into a directory that is already in $PATH, i.e. ln -s /home/arun/Desktop/scripts/myMasterScript.sh /usr/local/bin/

  • Sounds like the problem is/was that /home/arun/Desktop/scripts/myMasterScript.sh just didn't exist - typo?

Just create a function:

function masterScript()
    if [ -e /home/arun/Desktop/scripts/myMasterScript.sh ]
        bash /home/arun/Desktop/scripts/myMasterScript.sh

And make sure your script is executable:

chmod 755 /home/arun/Desktop/scripts/myMasterScript.sh
  • That's the way i would do it. +1 . There's no need for script , if you can achieve same action in few lines of code. Functions are ideal for that. May 5, 2016 at 14:59

I tried this out .. I simply made it

alias masterScript="cd /home/arun/Desktop/scripts && myMasterScript.sh"

Make sure your masterScript.sh is executable by doing:

chmod +x masterScript.sh

If the script is not executable, the bash command cannot run it and you'll get these kind of error messages.

  • This is not true - try it with bash non-executable-file and bash will run it

  • Ah right.. the +x permission seems to only matter if run via ./masterScript.sh
