Quick and Temporary Named Commands

Url Encode
It only encodes non-Basic-ASCII chars, as they are the only ones not well readed by UTF-8 and ISO-8859-1 (latin-1). It converts all * C3 X (some latin symbols like ASCII-extended ones) and * C2 X (some punctuation symbols like inverted exclamation) ...UTF-8 double byte symbols to escaped form that every parser understands to form the URLs. I didn't encode spaces and the rest of basic punctuation, but supposedly, space and others are coded as \x20, for example, in UTF-8, latin-1 and Windows-cp1252.... so its read perfectly. Please feel free to correct, the application to which I designe that function works as expected with my assumption. Note: I specify a w=999, I didn't find a flag to put unlimited value. I just suppose very improbable surpass the de-facto 255 (* 3 byte max) = 765 bytes length of URL

Grep all non-ascii character in file
It will highlight non-ascii character in a file. those character can cause problem for some application parsing ascii file.

quickly backup or copy a file with bash
less symbols, tab completion. including # export SIMPLE_BACKUP_SUFFIX="_`date +%F`" in your .bashrc provides you to easily timestamp your files

Rename files in batch

ignore hidden directory in bash completion (e.g. .svn)
add it in ~/.bashrc install bash-completion

Print the IPv4 address of a given interface

Execute a command with a timeout
A timeout is great, but what if the command is taking longer than expected because it's hung up or ran into some other problem? That's where the -k option comes in. Run "some_command" and timeout after 30s. If the command is still running after 1 minute, it will receive a kill signal.
