array - passing values to sed command

i grep this file and had to delete some of the results with sed - it worked fine

casper@kops11>egrep "cancel|modify|submit" evntlog.89655.Fri | sed -e '/Confirm/d' -e '/Third/d' -e '/find/d' -e '/Local/d' -e '/Auto/d' -e '/GEcp/d' -e '/BookConnectSServer/d' -e '/ExecReport/d'

just for investigation sake - i piped the grep results into a different file and then i tried to create a simple array loop that would sed out the line one by one out of the new file - is there a way to pass values to sed?

casper@kops11> vi simplearray
casper@kops11> more simplearray
#!/bin/sh

names=( Confirm Third find Local Auto GEcp BookConnectSServer ExecReport )
$(names[@])

for name in $(names[@])
do
sed '/"$name"/d' evntlog2.89655.Fri
done

casper@kops11> chmod +x simplearray
casper@kops11> simplearray
simplearray: line 4: names[@]: command not found
simplearray: line 9: names[@]: command not found

The $( command ) part tells bash to run the string inside the brackets as a command. So right now your telling bash to run a variable as a command.
Either leave out the $( ) part or use $( echo names[@] ).

Or, do it in Perl:

IgnoreKeywords.pl:

Code:

#!/usr/bin/perl -w



my @names = ("Confirm", "Third", "find", "Local", "Auto", "GEcp", "BookConnectSServer", "ExecReport");



while (<STDIN>) {

  chomp;

  my $match = 0;



  foreach $name (@names) {

    if ( $_ =~ m/$name/ ) { $match++ }

  }



  if ( $match == 0 ) { print $_, "\n" }

}

Execution:

Code:

$ < evntlog.89655.Fri IgnoreKeywords.pl

perhaps that should be

Code:

for name in "${names[@]}"

if you're going to read from a file it should be:

Code:

for name in $(<file)

Code:

while read name; do

  ...

done < file

Code:

# if you're going to read standard input

while read -u 4 name; do

  ...

done 4< file
