ls command - list files containing a specific string in file name and belong to specific type Is it possible for an `ls` command to return a list of files containing "PRO" in its file name and belong to pli file type? I have researched and identified that `ls -c -lt *.PLI` will return a files of ".pli" type and `ls -c -lt *PRO*` will return file which has PRO in its file name. Example: If the folder contains: * aaaaaPROaaaaa.PLI * aaaaaPROaaaaa.PSO * aaaaaPROaaaaa.txt * bbbbbPRObb.PLI * bbbbbPRObb.txt ... then I need the `ls` command to return only _`aaaaaPROaaaaa.PLI and bbbbbPRObb.PLI`_ If it is not achievable through the `ls` command, can we achieve it through the `find` command?

With `ls`, you can do:


ls -c -ltd -- *PRO*.PLI


With `find`:


find . ! -name . -prune -type f -name '*PRO*.PLI'


(note that `find` will include hidden files like `.xPRO.PLI` while the shell glob (`*PRO*.PLI`) will not by default).
