thank you for the quick reply but it does not seem to work. the pattern lines are still in the output and not in a seperated file.
Hello SDohmen,
You could redirect the output to a Output_file as follows then.
Code:
awk 'FNR==NR{A[$1]=$1;next} ($1 in A){print}' pattern_file FS=";" main_file > Output_file
EDIT: In case you need Output_file for matches and non-matches both then following may help you in same then.
Code:
awk 'FNR==NR{A[$1]=$1;next} ($1 in A){print >> "Output_match_found_file"} !($1 in A){print >> "Output_match_NOT_found_file"}' pattern_file FS=";" main_file
Thanks,
R. Singh

grab-account
GRAB-ACCOUNT(8) chiark utilities GRAB-ACCOUNT(8)NAME
grab-account - add new account synchronised to remote system
SYNOPSIS
grab-account local-user source [remote-user]
DESCRIPTION
grab-account reconfigures sync-accounts to start synchronising a specified local user (which may not yet exist) from a specified remote
system, and then invokes sync-accounts once to synchronise from that source.
/etc/sync-accounts/createuser should contain a addhere line in the appropriate source section (ie, after host source). grab-account adds a
user local-user [remote=remote-user]
directive just before addhere and runs sync-accounts source.
EXIT STATUS
0 All went well.
any other
There were problems.
FILES
/etc/sync-accounts; See also sync-accounts(8).
ENVIRONMENT
See sync-accounts(8).
BUGS
There is no locking of /etc/sync-accounts so do not invoke grab-account from a script, or more than once at a time by hand. Do not edit
/etc/sync-accounts by hand and also simultaneously run grab-account.
The mechanism involving addhere is suboptimal. This should be done with an include feature in sync-accounts, so that grab-account does not
have to edit a configuration file that really belongs to the sysadmin.
