将文本文件中文件名的一部分与目录中的文件名进行比较（grep + awk）

Question

This is not exactly the easiest one to explain in a title.

I have a file inputfile.txt that contains parts of filenames:

file1.abc
filed.def
fileq.lmn

This file is an input file that I need to use to find the full filenames of an actual directory. The ends of the filenames are different from case to case, but part of them is always the same.

I figured that I could grep text from the input file to the ls command in said directory (or the ls command to a simple text file), and then use awk to output my full desired result, but I'm having some trouble doing that.

file1.abc is read from the input file inputfile.txt It's checked against the directory contents. If the file exists, specific directories based on the filename are created.

(I'm also in a Busybox environment.. I don't have a lot at my disposal)

Something like this...

cat lscommandoutput.txt \
        | awk -F: '{print("mkdir" system("grep $0"); inputfile.txt}' \
        | /bin/sh

Thank you.

Edit: My apologies for not being clear on this. The output should be the full filename of each line found in lscommandoutput.txt using the inputfile.txt to grep those specific lines.

If inputfile.txt contains:

file1.abc
filed.def
fileq.lmn

and lscommandoutput.txt contains:

file0.oba.ca-1.fil
file1.abc.de-1.fil
filed.def.com-2.fil
fileh.jkl.open-1.fil
fileq.lmn.he-2.fil

The extra lines that aren't contained in the inputfile.txt are ignored. The ones that are in the inputfile.txt have a directory created for them with the name that got grepped from lscommandoutput.txt.

/dir/dir2/file1.abc.de-1.fil/ <-- directory in which files can be placed in
/dir/dir2/filed.def.com-2.fil/
/dir/dir2/fileq.lmn.he-2.fil/

Hopefully that is a little bit clearer.

First, you win a useless use of cat award

Secondly, you've explained this really badly. If you can't describe the problem clearly in plain English it's not surprising you are having trouble turning it into a script or set of commands.

grep -f is a good way to get the directory names, but I don't understand what you want to do with them afterwards.

My problem now is using the outputted file with the one file I want to put the folders

Wut? What does "the one file I want to put the folders" mean? Where does the file come from? Is it the file named in inputlist.txt ? Does it go in the directory that it matched?

If you just want to create the directories you can do:

fgrep -f ./inputfile.txt ./lscommandoutput.txt | xargs mkdir

NB you probably want fgrep so that the input strings aren't treated as regular expressions and regex metacharacters such as . are ignored.
