sorry to reopen this post.....Smilie

thanks to your solutions things got better but i am having a hard time integrating a command that normally works into the awk "loop" :
Code:
echo $NEW_PATH|awk 'BEGIN{FS="[&][&]"}{for(i=1;i<=NF;i++) find $i -mtime +$RET -exec rm {} \;}'

returns the following error :
Code:
awk: BEGIN{FS="[&][&]"}{for(i=1;i<=NF;i++) find $i -mtime +$RET -exec rm {} \;}
awk:                                                                     ^ syntax error
awk: BEGIN{FS="[&][&]"}{for(i=1;i<=NF;i++) find $i -mtime +$RET -exec rm {} \;}
awk:                                                                        ^ backslash not last character on line

I dont undestand this last character issue.....Smilie

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
