I would do one ssh per host and ship the scripting to the remote host, for speed and simplicity.
For getting hosts from your config file, just:
For good error handling, echo each host, time and user as you start each, into a log. you can display the log to the terminal, too, with 'tee -a' or 'tail -f log_file &' (just remember to kill $!). Screens can go poof, and you should keep a report.
A user name can be a substring of any field (like roo or oot !), so put some boundaries in the grep:
Count 0/1 is a nicer test.
I am trying to think of a way to create user ids on multiple Linux systems in one fell swoop without logging onto each system indivually. Is there a way to do this with ssh commands?

I've had Linux when I was young, on one of our first computers and learned it pretty quickly... However, I've been working on Windows for about 7 years now and just made the switch back to Linux, Mandrake 9.1. So I have some problem with creating new user accounts. I could create one, but once I... (3 Replies)

I have a directory full of zip files.
How would I write a bash script to enumerate all the zip files, remove the ".zip" from the file name, create a directory by that name and unzip each zip file into its corresponding directory?
Thanks!

I have a script on about 15 hosts that I need to run for each host whenever I want (not crontab). Problem is, this script takes 5-10 mins to run for each host.

I have a script to detect if a host is pingable or not. The problem is that I would like it to put the nonpingable hosts in one file and the pingable hosts in another. I have come up with this so far:

It worked for me so I'm sharing it... (9 Replies)

zgrep
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.
