Convert ascii string to hex

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

echo "text" | od -t x1

Convert ascii string to hex

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.

Convert ascii string to hex

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"}'

Convert ascii string to hex

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

Function to output an ASCII character given its decimal equivalent

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.

Functions: iconv

Tags: cat bash ascii iconv nfo

Outputs files with ascii art in the intended form.

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
