"for I in `cat file`" is a dangerous use of backticks. It does not do what you think it does. Do
Code:
while read LINE do ... done < inputfile
There's better ways to get variables into awk, such as awk -v VAR="value" or awk 'expression' VAR=value FILENAME, no need to embed it in the expression.
So:
Code:
while read PAT
do
awk -v PAT="$PAT" 'PAT ~ $0 { P=1 } P ; /\);/ { P=0 }' inputfile
echo "@@@@@@@@"
done < pattern_file.txt > output.txt| Moderator's Comments: | ||

IGAWK(1) Utility Commands IGAWK(1) NAME
igawk - gawk with include files SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ... igawk [ all gawk options ] [ -- ] program-text file ... DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1). AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like @include getopt.awk in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path. OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports. EXAMPLES
cat << EOF > test.awk @include getopt.awk BEGIN { while (getopt(ARGC, ARGV, "am:q") != -1) ... } EOF igawk -f test.awk SEE ALSO
