expression, as shown below.
var=`head -1 file1`
awk '$0!~/$var/ {print $0}' file1 > file2
In the case above $var value literally considered for non-exists criteria. (3 Replies)

update-metainit
UPDATE-METAINIT(1) User Contributed Perl Documentation UPDATE-METAINIT(1)NAME
update-metainit - Generates init scripts
SYNOPSIS
update-metainit [--remove initname [--purge] ]
DESCRIPTION
Metainit solves the problem of writing good init scripts. Instead of manually creating these important files, they are derived from a
declaritive description in the metainit files in /etc/metainit. These files can be shipped with packages or created by the local adminis-
trator.
If update-metainit called without argument, it will regenerate init scripts for all the files in /etc/metainit. The generated files contain
a large warning in form of a comment that they will be overridden. Modifications are preferably done in the files in /etc/metainit and made
effective by running update-metainit. If needed, the administrator can prevent modified init files by removing the warning comment.
OPTIONS --remove initname
This command will remove any generated and non-modified scripts that were created by the metainit file with the name initname.
--purge
Only usable with --remove. Will remove the generated files even if modified.
