Cygwin ls command not found

If you are a linux enthusiast and really miss those greps and sed/awks on the windows box, you've probably installed cygwin. You tried running it either by double-clicking the cygwin icon on your desktop or the cygwin.bat file in your "C:\cygwin" directory and got the bash-3.X$ prompt. However, although the pwd or cd commands work, if you try ls, it says:"ls: command not found".

Here is what you need to do to fix it:
  1. Right click on "My Computer" -> Properties -> Advanced -> Environment Variables
  2. Add a new environment variable, called CYGWIN_HOME and set its value to C:\cygwin
  3. Edit the PATH environment variable and add C:\cygwin\bin to it (usually separated by a ';').
  4. Just click okay, exit any command prompts or bash shells (over cygwin) you may have open, and open it again - it'll work!
Note: this assumes that you have installed cygwin at C:\cygwin. If you've kept it someplace else, please modify the above accordingly.

    Thanks a lot! I spent so much time downloading
    Cygwin in order to learn Linux console
    commands - and it didn't know even about ls!

    I've translated your tip into Russian and
    posted to my blog. Hope, you don't mind

    hi there!

    But should you unistall the "run" package from Cygwin...

    Even though the Env. variable in Windows reads sequential and if we keep the Cygwin path the last - still may cause prob?


    Cheers!

    As a side note, you may also want to add:

    C:\cygwin\usr\sbin to the PATH variable

    Thanks for blogging about useful commands.
    Ls command basically displays the content of directory in sorted alphabetically.
    If you have millions of files/directories, ls command hangs because of sorting.
    Ls –U ouput files without sorting and more useful
    Please see more about Ls command examples in Linux/Unix

    For those of you using win 10 and the above solution does not work, instead add C:\cygwin64\bin to PATH. it will work.

  40. UnknownAugust 23, 2019 at 3:15 AM

    check PATH in C:\cygwin64\home inside file called .profile
