Another approach:
Code:
SPECIAL_CHARS='& ;'
ESCAPE_CHAR='\'
echo 'abcd fkaj&dsdsd' | awk -v SC="$SPECIAL_CHARS" -v EC="$ESCAPE_CHAR" '
        BEGIN {
                n = split ( SC, A )
        }
        {
                for ( i = 1; i <= n; i++ )
                        gsub ( A[i], EC "\\&", $0 )
                print
        }

Test::use::ok(3)					User Contributed Perl Documentation					  Test::use::ok(3)

NAME
Test::use::ok - Alternative to Test::More::use_ok SYNOPSIS
use ok 'Some::Module'; DESCRIPTION
According to the Test::More documentation, it is recommended to run "use_ok()" inside a "BEGIN" block, so functions are exported at compile-time and prototypes are properly honored. That is, instead of writing this: use_ok( 'Some::Module' ); use_ok( 'Other::Module' ); One should write this: BEGIN { use_ok( 'Some::Module' ); } BEGIN { use_ok( 'Other::Module' ); } However, people often either forget to add "BEGIN", or mistakenly group "use_ok" with other tests in a single "BEGIN" block, which can create subtle differences in execution order. With this module, simply change all "use_ok" in test scripts to "use ok", and they will be executed at "BEGIN" time. The explicit space after "use" makes it clear that this is a single compile-time action. SEE ALSO
