If you need to remove directories from the listing, something like this perhaps.

Code:

ls -salt | sed '/^total/d;/^ *[1-9][0-9]* d/d;q'

The sed script is shorthand for grep -v '^total' | grep -v '^ *[1-9][0-9]* d' | head -1 -- combining those into a single script is somewhat more elegant IMHO, but the pipeline with multiple greps and a head will work fine as well. The first grep is to remove the "total 12345" printed on the first line, and the second grep is to remove any directories; the regular expression matches beginning of line, followed by optional spaces, followed by a number (this is what ls prints with the -s option on my system) followed by a space and a d which indicates that the entry is a directory. Without the -s option, you would simply remove any line with d as its first character; that's grep -v '^d'

zgrep

ZGREP(1)						      General Commands Manual							  ZGREP(1)

NAME

       zgrep - search possibly compressed files for a regular expression

SYNOPSIS

       zgrep [ grep_options ] [ -e ] pattern filename...

DESCRIPTION

       Zgrep  invokes  grep  on  compressed  or  gzipped  files.   These  grep	options  will  cause  zgrep  to  terminate  with  an  error  code:
       (-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*).  All other options specified are passed directly to grep.  If no file is specified,  then  the
       standard input is decompressed if necessary and fed to grep.  Otherwise the given files are uncompressed if necessary and fed to grep.

       If the GREP environment variable is set, zgrep uses it as the grep program to be invoked.

EXIT CODE

       2 - An option that is not supported was specified.
