Top Forums UNIX for Beginners Questions & Answers What script would I use to count the number of a term and its opposite? Post 303041738 by RudiC on Tuesday 3rd of December 2019 05:43:41 AM

With grep and friends you'll get one count per run, so you'll have to go through the file twice. Might not be a problem with small files, but resource consumption increases with sizes. Taylor your solution with a little script like e.g.
Code:
awk -v"PAT=done" '$0 ~ PAT {PRES++; next} {ABS++} END {print PRES ORS ABS}' file

or, if you need it case insensitive,

Code:
awk -v"PAT=done" 'tolower($0) ~ tolower(PAT) {PRES++; next} {ABS++} END {print PRES ORS ABS}' file

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. AUTHOR
