But autoconf.info says: `egrep' POSIX 1003.1-2001 no longer requires `egrep', but many older hosts do not yet support the POSIX replacement `grep -E'. To work around this problem, invoke `AC_PROG_EGREP' and then use `$EGREP'. What about using the dumber regexp + grep '\\Declare[a-zA-Z]*Class' "$file" \ It is less accurate, but should be good enough for what we need. If we want to be robust and catch \DeclareMyWeirdClass, I am sure that it is possible to add a clause like -e 's/\\Declare[a-zA-Z]*Class//' Angus, would that work? JMarc
