It "should" only ever break software that uses them to configure shebang lines, but this is uncommon for anything other than SH and BASH. Attempting to treat EGREP, FGREP, and EGREP_TRADITIONAL as paths of any sort will be outright broken, even, since "/bin/grep -E" can't be used as a full filepath anyway. What circumstances other than a shebang might break without a full path? -- Eli Schwartz
