Find the package that installed a command

Use a var with more text only if it exists
See "Parameter Expansion" in the bash manpage. They refer to this as "Use Alternate Value", but we're including the var in the at alternative.

find only current directory (universal)
you must be in the directory to analyse report all files and links in the currect directory, not recursively. this find command ahs been tested on hp-ux/linux/aix/solaris.

Remove security limitations from PDF documents using ghostscript (for Windows)
#4345 also works under windows

find all active IP addresses in a network
I just added the args [arp-scan --localnet] which works for Debian users, because the package 'arp' has name 'arp-scan', and it doesn't works with the argument 'arp'.

Not a kismet replacement...
If you're like some individuals who rely on ndiswrapper and cannot use kismet, this command may be of service. watch -n .5 "iwlist wlan0 scan | egrep 'ESSID|Encryption'" Or... watch -n .5 "iwlist wlan0 scan | egrep 'ESSID|Encryption' | egrep 'linksys'" :-) Hopefully you'll find some dd-wrt compatible routers.

Create a single-use TCP (or UDP) proxy
Redirect the local port 2000 to the remote port 3000. The same but UDP: $ nc -u -l -p 2000 -c "nc -u example.org 3000" It may be used to "convert" TCP client to UDP server (or viceversa): $ nc -l -p 2000 -c "nc -u example.org 3000"

copy hybrid iso images to USB key for booting from it, progress bar and remaining time are displayed while copying

shuffle lines via perl
Same, without modules... Probably smarter option: just use the shuf command or even sort -R.

Batch file name renaming (copying or moving) w/ glob matching.
