This patch corrects the following: - Corrects a problem with the fgrep command, when it is used with the -s flag all output is suppressed. - Fixes a limitation problem with the grep and fgrep commands. If the line length is too long, grep displays a "wordlist too large" error message and fgrep displays "input too long" error message. This patch fixes several problems with fgrep: 1) The command fgrep -f searchlist gets the following error message: wordlist too large if the searchlist is too long, in the test case it was 1500 entries. 2) The command fgrep -f searchlist displays datafiles verbatim if the searchlist has blank lines. This patch fixes a problem in which the grep command with the -w switch does not work as documented.
