Hello: Does anyone know how to use ‘awk’ in a script? It must have a different syntax than the unix analog, as does the ‘grep’ command. For grep, the syntax in the c-shell is: “grep ‘string’ , but for Perl the delimiters are slashes: $x = grep / string/ line. Maybe the same thing is going on with Perl.
I have searched the following sources with no help on awk: perldoc -f ‘awk’ ‘Beginning Perl’ by S. Cozen ‘CGI101’ and the O’Reilly books: ‘Learning Perl’ aka the llama book ‘Intemediate Perl’ ‘Advanced Perl’ ‘CGI Programming with Perl’ I have a file called /tmp/file.txt with one line: field xxxx for grepping on xxxx, the script is: #!/usr/bin/perl -w use CGI::Carp qw(fatalsToBrowser); use CGI qw(:standard -no_xhtml); #use CGI ':standard'; use strict; use diagnostics; my $q = new CGI; print $q->header; print $q->start_html(-title=>"mygrep"); my @infile; my $q = new CGI; open (FILEIN, "/tmp/file.txt") or die "Can't open /tmp/file.txt for reading: $!\n!"; open (FILEOUT, ">/tmp/out.txt") or die "Can't open /tmp/out.txt for writing: $!\n!"; system "chmod 755 /tmp/out.txt"; while ( defined(my $line=<FILEIN>) ){ chomp($line); push (@infile,$line); } my @zoom = grep(/xxxx/,@infile); #looks for 'xxxx' in @infile foreach (@zoom){ print $q->center($q->h3("\nNext line containing 'xxxx' is: \n"), $q->h3("$_\n"), $q->h3("_ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _") ); } print $q->center($q->h2(" grep program is finished!\n")); _______________________________________________________________________ The script works as it should for grep, but what if I want to output $NF (=xxxx) when a line has the string ‘field’ in it? There must be a way, but I can't find it. Thank you. Mary -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] http://learn.perl.org/
