Mac, ip, and hostname change - sweet!

The command above has been changed due to very good constructive criticism - thanks x 2! This command can be used after acquiring mac's, ip's and hostname's or any of the above from a freshly scanned LAN. User must be root, and remember to change your settings on your network managing software manually (Fedc10 NetworkManager Applet 0.7.1 is mine) instead of 'auto DHCP'. You can also substitute eth0 for wlan0 etc - be good and ENJOY!

Periodically loop a command

You can use this to loop any command to periodically see the output. while true; do [YOUR COMMAND HERE]; sleep [# of seconds]; done; Alternatively, you can put it in a simple shell script to save typing! #/!bin/bash while true; do $1; sleep $2; done; /path/to/script.sh "ifconfig eth0 | grep 'inet addr:'" 60 Show Sample Output
This is sample output - yours may be different.
```
inet addr:192.168.1.2  Bcast:192.168.1.255  Mask:255.255.255.0

show your private/local ip address

This assumes your local ip starts with 192.something (e.g. 192.168), it greps ifconfig output for an ip that starts with 192, then strips the extra garbage (besides the ip) Maybe `ifconfig | grep addr | grep Bcast` would also do it Show Sample Output
This is sample output - yours may be different.
```
192.168.1.104
```

ifconfig | grep addr:192 | sed s/Bcast.*// | sed 's/^.*inet addr://'

What's this?

commandlinefu.com is the place to record those command-line gems that you return to again and again. That way others can gain from your CLI wisdom and you from theirs too. All commands can be commented on, discussed and voted up or down.

Find

A lot of X applications accept --geometry parameter so that you can set application size and position. But how can you figure out the exact arguments for --geometry? Launch an application, resize and reposition its window as needed, then launch xwininfo in a terminal an click on the application window. You will see some useful window info including its geometry.

Execute a command without saving it in the history

Prepending one or more spaces to your command won't be saved in history. Useful for pr0n or passwords on the commandline. Tested on BASH.

watch snapshots commit in VMware ESX

To monitor .vmdk files during snapshot deletion (commit) on ESX only (ESXi doesn't have the watch command): 1. Navigate to the VM directory containing .vmdk files. # watch "ls -tough --full-time *.vmdk" where: -t sorts by modification time -o do not list group information (to narrow the output) -u sorts by access time -g only here for the purpose to easily remember the created mnemonic word 'tough' -h prints sizes in human readable format (e.g., 1K 234M 2G) --full-time sets the time style to full-iso and does not list user information (to narrow the output) optionally useful parameters to the watch command: -d highlight changes between updates -n seconds to wait between updates (default is 2) -t turn off printing the header

one-line log format for svn

the output of svn log is annoying to grep, since it spreads the useful info over multiple lines. This compacts the output down to one line so eg you can grep for a comment and see the rev, date & committer straight away. Updated: MUCH shorter, easier to remember. Now it just replaces newlines with spaces, except on '---' lines.
