Do nothing if column1 is found
Hello,
I have stucked at one point.
When I run the script, I am asking the script to search in database file and if it's found, do nothing and proceed to next line in database file.

Code:
#!/bin/bash
./extract_email.pl output2 > database
while read -r COL1
    X=$(grep $COL1 database )
    if [[ -z $X ]] ; then
        echo "false"
        exit
else 
do
sed -n '1,2p' /var/test/test.txt > $COL1
sed -e '1,2d' /var/test/test.txt > /var/test/test2.txt
mail -s "mail subject is here" -a "From: info@mymail.net" $COL1 < $COL1
mv $COL1 /var/test/database_pool/
done < database
rm output*
rm *.host
exit 0

when i run the script, it says " syntax error near unexpected token `do' "

Could you please let me know how "do nothing" if col1 is already in my database.

Thanks in advance
Boris

LEARN ABOUT NETBSD

netgroup_mkdb

NETGROUP_MKDB(8)					    BSD System Manager's Manual 					  NETGROUP_MKDB(8)

NAME

     netgroup_mkdb -- generate the netgroup database

SYNOPSIS

     netgroup_mkdb [-o database] [file]

DESCRIPTION

     netgroup_mkdb creates a db(3) database for the specified file.  If no file is specified, then /etc/netgroup is used.  This database is
     installed into /var/db/netgroup.db.  The file must be in the correct format (see netgroup(5)).

     The options are as follows:

     -o database
	     Put the output databases in the named file.

     The databases are used by the C library netgroup routines (see getnetgrent(3)).

     netgroup_mkdb exits zero on success, non-zero on failure.

FILES

     /var/db/netgroup.db       The current netgroup database
     /var/db/netgroup.db.tmp   A temporary file
     /etc/netgroup	       The current netgroup file

SEE ALSO

     db(3), getnetgrent(3), netgroup(5)

BUGS

     Because netgroup_mkdb guarantees not to install a partial destination file it must build a temporary file in the same file system and if suc-
     cessful use rename(2) to install over the destination file.

     If netgroup_mkdb fails it will leave the previous version of the destination file intact.
