if [[ $? == 0 ]]
then
        mv  main_file main_file_Original
        mv  Output_match_NOT_found_file main_file
else
        echo "Please check there seems to be an issue with awk command."
fi

Above code will create a backup for main_file with name main_file_Original and remvove non-matching lines from main_file too, let me know if this helps you.


Thanks,

I just tested the code as follows (adapted to my enviroment)
Code:
awk 'FNR==NR{A[$1]=$1;next} ($1 in A){print >> $PAD/raw4.csv} !($1 in A){print >> $PAD/removed.csv}' $VOEG/niet_gebruiken_ean.csv FS=";" $PAD/raw3.csv

but it does not seem to create the files. The error i am getting is as follows:

awk: 1: unexpected character '.'
awk: 1: unexpected character '.'
awk: cannot open /srv/prijslijst/lev/raw4.csv (No such file or directory)

I tried changing the $PAD variable to the dir itself but it does not change the output. From the shell itself it works fine.
