Ubuntu – List files of particular extension

file formatls

Ok this is strange. I am using this code,

ls *.prj

To list all the files with the .prj extension in the dir but I am getting this error,

bash: /bin/ls: Argument list too long

I eventually wish to get the count of files and I was using,

ls *.prj | wc -l

But even this command is giving the same error. Any idea where I am going wrong?

  • Nothing, there is a limit on the number of argument bash can deal with. Do

    ls | grep '\.prj$' | wc -l
