I have the two perl command

perl  -pe "s/\b$a\b/$b/g if m/param1 /"  test


perl  -pe "s/\b$a\b/$b/g unless /^#/" test

how to use combine the if m/somthing/ and the unless /something/

for example

[[email protected] tmp]#  perl  -pe "s/\b$a\b/$b/g if m/param1/ unless /^#/"  test
syntax error at -e line 1, near "m/param1/ unless"

but its now work THX
