Full Discussion: Translate grep to awk
Top Forums Shell Programming and Scripting Translate grep to awk Post 302752229 by Yoda on Sunday 6th of January 2013 09:25:17 AM

Code:
sed -n "2,10p" lfile | awk '/error/&&!/memory/{c++}END{print c}'
sed -n "2,10p" lfile | awk '/error/&&!/memory/'
sed -n "2,10p" lfile | awk '/error/&&/memory/{c++}END{print c}'
sed -n "2,10p" lfile | awk '/error/&&/memory/'

Note: You can get rid of sed as well using NR variable in awk
Code:
awk 'NR>=2&&NR<=10&&/error/&&!/memory/{c++}END{print c}' lfile
awk 'NR>=2&&NR<=10&&/error/&&!/memory/' lfile
awk 'NR>=2&&NR<=10&&/error/&&/memory/{c++}END{print c}' lfile
awk 'NR>=2&&NR<=10&&/error/&&/memory/' lfile

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.

SEE ALSO

     egrep(1), fgrep(1), grep(1), gzip(1), zcat(1)
