Could you not also use find to drive this rather than building your own where you have to feed it a list? You don't give much information about what else there is, but this might help:-
If the file name search is for path names, then you could do something more like this:-
Code:
find *save[0-9][0-9]* -type f -exec grep "$pattern" {} \;
Do either of these give you an option? They should be more efficient than calling grep for every parameter, especially as the list gets longer and would reduce the risks of too long a command line getting rejected.
You could even combine them if that helps:
If you want all files that match save[0-9][0-9] and finish .sh then you can
find . -name "*save[0-9][0-9]*.sh" .....
If you want files in directories that match save[0-9][0-9] and finish .sh then you can
find *save[0-9][0-9]* -name "*.sh" ......
If you want some other variation or combination we can probably help there too.

Hi,
I need to look for a config file (ldap.conf) and pick the latest modified file.
`locate` tells me there are many ldap.conf's, some in /etc, /usr, /home, etc.
Is there some way I can sort them by last modified time via bash?
I was thinking maybe I could pipe the output of `locate` to `ls... (4 Replies)

We need to have many of our users all send encrypted files to a single FTP server. The problem, if I understand how encryption/decryption works (which I don't), is that each user would normally have their own private and public key.

zegrep
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.
