Top Forums Shell Programming and Scripting Continue Execution Based On List Post 302885123 by RudiC on Thursday 23rd of January 2014 03:46:51 PM

So you have a list of file names, a directory full of files, and the intersection of both must match a pattern. It may be a bit tedious to find out the optimum way to boil that down to the actual set of files to be worked upon. Scrutinizer has provided one example; try this as an alternative:
Code:
ls $(grep TM_ICP_EDW_FIN04-ACCOUNT_CONSOL_.*\.csv list.txt) >pass.txt 2>/dev/null

Watch out - grep takes a regex, not a shell pattern!

ZGREP(1)						    BSD General Commands Manual 						  ZGREP(1)

NAME
zgrep, zegrep, zfgrep -- print lines matching a pattern in gzip-compressed files SYNOPSIS
zgrep [grep-flags] [--] pattern [files ...] zegrep [grep-flags] [--] pattern [file ...] zfgrep [grep-flags] [--] pattern [file ...] DESCRIPTION
zgrep runs grep(1) on files or stdin, if no files argument is given, after decompressing them with zcat(1). The grep-flags and pattern arguments are passed on to grep(1). If an -e flag is found in the grep-flags, zgrep will not look for a pattern argument. zegrep calls egrep(1), while zfgrep calls fgrep(1). EXIT STATUS
In case of missing arguments or missing pattern, 1 will be returned, otherwise 0. SEE ALSO
egrep(1), fgrep(1), grep(1), gzip(1), zcat(1) AUTHORS
