Displays a scrolling banner which loops until you hit Ctrl-C to terminate it. Make sure you finish your banner message with a space so it will loop nicely.
Files containing ascii art (e.g. with .nfo extension) are typically not correctly reproduced at the command line when using cat. With iconv one can easily write a wrapper to solve this:
#!/bin/bash
if [ -z "$@" ]; then echo "Usage: $(basename $0) file [file] ..."
else iconv -f437 -tutf8 "$@"; fi
exit 0
Not so useful. Just a cool feature.
Prints out an ascii chart using builtin bash! Then formats using cat -t and column.
The best part is:
echo -e "${p: -3} \\0$(( $i/64*100 + $i%64/8*10 + $i%8 ))";

I've corrected the function. My octal conversion formula was completely wrong. Thanks to pgas at http://mywiki.wooledge.org/BashFAQ/071 for setting me straight. The new function is from pgas and is very fast. Show Sample Output
Removes ANSI color and end of line codes to the [{attr1};...;{attrn}m format.
If you're going to use od, here's how to suppress the labels at the beginning. Also, it doesn't output the \x, hence the sed command at the end. Remove it for space separated hex values instead Show Sample Output
just a bit simpler
You can use "decode()" in a similar manner:
python -c 'print "68656c6c6f".decode("hex")'

strips html from stdin Show Sample Output
Optionally, pipe the output into http://sed.sourceforge.net/grabbag/scripts/html2iso.sed Or: wget -qO - http://www.asciiartfarts.com/random.cgi | sed -n '//,//p' | sed -n '/ Show Sample Output
Converts the ascii text to hex from bash. Check the sample output. Show Sample Output
Here's a version that uses perl. If you'd like a trailing newline:
perl -pe 's/(.)/sprintf("\\x%x", ord($1))/eg; END {print "\n"}'
Even adds a newline.
It will highlight non-ascii character in a file. those character can cause problem for some application parsing ascii file.
Slug the part of an URL which identifies a page using human-readable keywords. Slugs are used to construct friendly URLs (often for permalinks) that are easy to type, descriptive, and easy to remember. Show Sample Output
Doesn't fail for percent sign now.
Can be installed in the root crontab if you want it to update your motd. If not on ubuntu you need to change /usr/share/cowsay/cows/* to the location of your cow files. Show Sample Output
Same as another one I saw, just with a cleaner sed command Edit: updated the sed command to use the [[:xdigit:]] character class - more portable between locales Note that it will have a newline inserted after every 32 characters of input, due to the output of xxd Show Sample Output
Just use "od" and it can also dump in decimal or octal. (use -t x1 and not just -x or it confuses the byte order) There is a load of other formatting options, I'm not sure if you can turn off the address at the start of the line. Show Sample Output
