Top Forums UNIX for Dummies Questions & Answers Running two command at the same time Post 302147321 by gus2000 on Monday 26th of November 2007 10:36:01 AM

You didn't say which shell you were using, but something like this should work:

Code:
grep $PAT $FILE > foo.bar &
typeset PID=$!
echo "Processing...\c"
while ps $PID > /dev/null 2>&1; do
  echo ".\c" && sleep 1
done
echo "Done."

The "\c" in the echo command stops the CR/LF (ksh). Other shells probably use "echo -n" instead.

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
