SEARCH SCRIPT

From: Guy Hammer <guyh@teleport.com>

Here is a script to save a bunch of keystrokes. Make a file /usr/local/bin/psgrep . Paste the following into it:

---start---
#!/bin/bash
#
# psgrep - search for a process by pattern.

ps -ef | grep -v grep | grep $1
---end---

Make the script world executable. Now you just have to type 'psgrep matrix'.

Floppy Disks

A useful format and two copying commands.

Format

fdformat /dev/fd0u1440 

Copying

cat YOURFILE > /dev/fd0u1440 note the redirect symbol'>'

To make an exact copy, including the boot sector just do the following;

dd if=/dev/fd0 of=/dev/fd1

This is also a good way to make a backup of a floppy, or make it easy to make multiple copies.

dd if=/dev/fd0 of=filename
Where 'if' means Input File and 'of' means Output File
