note tachyon <p>OK so I lied (it was just a little one!) It really uses the abortive GNU regex syntax that is just different enough from Perl to s!+t you if you really know perl REs.....it is like grep. My usual greps are called re and re! linked into /usr/bin. They look like: <code> [root@devel3 root]# cat /usr/bin/re #!/usr/bin/perl die "Usage re [RE]\nFull Perl grep on STDIN\n" unless @ARGV == 1; my $re = qr/$ARGV[0]/; while(<STDIN>) { print if m/$re/; } [root@devel3 root]# cat /usr/bin/re! #!/usr/bin/perl die "Usage re [RE]\nFull Perl grep on STDIN\n" unless @ARGV == 1; my $re = qr/$ARGV[0]/; while(<STDIN>) { print if ! m/$re/; } [root@devel3 root]# cat some.file | re "some perl re" </code> <div class="pmsig"> <div class="pmsig-80749"> <p>cheers <p><font color="#0000ff">tachyon</font> </div></div> 333737 333752
