I have file names that looks like this:
act-art-atr-phm-pro-psy act-art-atr-phm-pro-sta act-art-atr-pro-psy-rel-sta act-art-atr-pro-tme act-art-atr-psy act-art-atr-psy-qud-sta act-art-atr-psy-sta act-art-atr-rel act-art-atr-sta act-art-com I want to cat files that contain at least two specific words (separated by "-") that I manually indicate.
For instance: I want to cat all files that contain at least "act" and "psy", thus the resulting file would contain all of the contents from the files
act-art-atr-phm-pro-psy act-art-atr-pro-psy-rel-sta act-art-atr-psy act-art-atr-psy-qud-sta act-art-atr-psy-sta I am not sure of a straight-forward regular expression that would be able to do this, as the order of the file names is unique for each files.
Is there a particular regex that can search for files containing at least 2 of the three-lettered names separated by "-" that I can use to cat all of the corresponding files?
Or even a more efficient way to handle this task, if my proposed regex +cat strategy is not the best.

It seems that the filenames contain the terms in alphabetical order. So you could say
cat `ls -1 | grep 'act.*psy'` or
cat $(ls -1 | grep 'act.*psy') If you want to get the file names which are separated by - with your words:
ls -1 | grep 'word1-word2' If you want to print all the contents of those files:
cat $(ls -1 | grep 'word1-word2' )
