Delete Comments
Hello i am back
,
i have a prolem. I want to Delete the IPs which are in Comments.
Input
PHP Code:
192.168.0.1
192.168.0.2
#192.168.0.3
#192.168.0.4 - when TAB or Space, delete too.
/*192.168.0.5
192.168.0.6
192.168.0.7*\
Output
PHP Code:
192.168.0.1
192.168.0.2
My solution is
PHP Code:
sed -e '/^#/d' -e '/^$/d' or sed -ne '/^[[:blank:]]*[^#]/p'
but it isnīt that what i want.
this removes only # with space or TAB
PHP Code:
sed '1p; /^[[:blank:]]*#/d; s/[[:blank:]][[:blank:]]*#.*//'
thx

ZGREP(1) General Commands Manual ZGREP(1)
NAME
zgrep - search possibly compressed files for a regular expression
SYNOPSIS
zgrep [ grep_options ] [ -e ] pattern filename...
DESCRIPTION
Zgrep invokes grep on compressed or gzipped files. These grep options will cause zgrep to terminate with an error code:
(-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*). All other options specified are passed directly to grep. If no file is specified, then the
standard input is decompressed if necessary and fed to grep. Otherwise the given files are uncompressed if necessary and fed to grep.
If the GREP environment variable is set, zgrep uses it as the grep program to be invoked.
EXIT CODE
2 - An option that is not supported was specified.
