Greetings everyone. Right now I am working on a script to be used during automated deployment of servers. What I have to do is remove localhost.localdomain and localhost6.localdomain6 from the /etc/hosts file. Simple, right? Except most of the examples I've found using sed want to delete the entire line.
Here's the example contents of the file:
Code:
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost
::1 localhost6.localdomain6 localhost6
172.30.0.133 loghost
Here's the regex I was planning to use:
Code:
/\bl.*(n|n6)\b/g
I tested it and it looks like its working. Now I just have to figure out how to use it in sed. The file needs to be left in place, so I know it'll be starting something along these lines...
sed -i (delete) /\bl.*(n|n6)\b/g /etc/hosts
Any help would be very much appreciated; I'm still getting used to using sed and 90% of the examples still look completely cryptic to me.
My ultimate goal is to have the /etc/hosts file look like this:
Code:
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost
::1 localhost6
172.30.0.133 loghost

Ok, so I have bunch of files that are named "orange__file_name.asm" and I want to batch rename them to "file_name.asm" I know that using "ls | sed s/orange__//" will get rid of the part of the file name I do not want. But how do I combine that with the mv command to actually do it?
Thanks

uudemon.cleanu
uudemon(4) Kernel Interfaces Manual uudemon(4)NAME
uudemon.admin, uudemon.cleanu, uudemon.hour, uudemon.poll - Administrative shell scripts for polling remote systems, cleaning up spool
directories, reporting status to the system administrator, and routine invocations of the uuxqt and uusched daemons
SYNOPSIS
These shell scripts reside in the following directory:
/usr/lib/uucp
DESCRIPTION
All the scripts can be run from the command line or can be run automatically by the cron daemon. To automatically run the scripts, remove
the comment character (#) from the beginning of the relevant line in the /var/spool/cron/crontabs/uucp file.
This script reports status to the system administrator. It issues the uustat command to find out the status of uucp jobs. It mails the
results to the uucp login ID. The script may be modified to send mail to any login ID such as the uucp administrative login ID (uucpa) or
root. This script cleans up the /var/spool/uucp and /var/spool/uucppublic directories by running the uucleanup command. The uucleanup com-
mand is run with the following parameters: -C7, -D7, X2, -o2, -W1. This script runs the uusched and uuxqt daemons in the background. This
script polls the systems listed in the /usr/lib/uucp/Poll file. The uudemon.poll script should be scheduled before the uudemon.hour
script. This allows uudemon.poll to create any command files before cron runs the uudemon.hour script.
FILES
Contains the uudemon.admin, uudemon.cleanu, uudemon.hour and uudemon.poll files. Contains the uucp file.
