Why I can t change directories using cd

Question

I m trying to write a small script to change the current directory to my project directory      bin bash cd  home tree projects java   I saved this file as proj  added execute permission with chmod  and copied it to  usr bin  When I call it by  proj  it does nothing  What am I doing wrong

The cd in your script technically worked as it changed the directory of the shell that ran the script  but that was a separate process forked from your interactive shell   A Posix-compatible way to solve this problem is to define a shell procedure rather than a shell-invoked command script   jhome        cd  home tree projects java     You can just type this in or put it in one of the various shell startup files

When you fire a shell script  it runs a new instance of that shell   bin bash    Thus  your script just fires up a shell  changes the directory and exits   Put another way  cd  and other such commands  within a shell script do not affect nor have access to the shell from which they were launched

You can use   to execute a script in the current shell environment     script name   or alternatively  its more readable but shell specific alias source   source script name   This avoids the subshell  and allows any variables or builtins  including cd  to affect the current shell instead

If you are using fish as your shell  the best solution is to create a function  As an example  given the original question  you could copy the 4 lines below and paste them into your fish command line   function proj    cd  home tree projects java end funcsave proj   This will create the function and save it for use later  If your project changes  just repeat the process using the new path   If you prefer  you can manually add the function file by doing the following   nano    config fish functions proj fish   and enter the text   function proj    cd  home tree projects java end   and finally press ctrl x to exit and y followed by return to save your changes    NOTE  the first method of using funcsave creates the proj fish file for you

Shell scripts are run inside a subshell  and each subshell has its own concept of what the current directory is  The cd succeeds  but as soon as the subshell exits  you re back in the interactive shell and nothing ever changed there   One way to get around this is to use an alias instead   alias proj  cd  home tree projects java

You re doing nothing wrong   You ve changed the directory  but only within the subshell that runs the script   You can run the script in your current process with the  dot  command     proj   But I d prefer Greg s suggestion to use an alias in this simple case

This should do what you want  Change to the directory of interest  from within the script   and then spawn a new bash shell      bin bash    saved as mov dir sh cd   mt v3 rt linux-rt-tools  bash   If you run this  it will take you to the directory of interest and when you exit it it will bring you back to the original place   root intel-corei7-64      mov dir sh  root intel-corei7-64   mt v3 rt linux-rt-tools  exit root intel-corei7-64      This will even take you to back to your original directory when you exit  CTRL d
