1#! /bin/sh 2 3# This filter should be applied to *every* stderr result. It removes 4# Valgrind startup stuff and pid numbers. 5# 6# Nb: The GNU and BSD implementations of 'sed' are quite different, so 7# anything remotely complicated (e.g. "\(a\|b\)" alternatives) can't be 8# easily done. Use Perl instead for any such cases. 9 10dir=`dirname $0` 11 12# Remove ==pid== and --pid-- and **pid** strings 13perl -p -e 's/(==|--|\*\*)[0-9]{1,7}\1 //' | 14 15# Remove any --pid:0: strings (debuglog level zero output) 16sed "/^--[0-9]\{1,7\}:0:*/d" | 17 18# Remove "Command: line".
