Machine Type: i686-pc-cygwin, i686-pc-msys, x86_86-linux-gnu,
x86_64-Apple-Darwin
Bash Version: 4.3
Patch Level: 30
Release Status: release
Description:
Bash has different escape syntaxes for `echo -e`, `printf` and
`$'ANSI_C_style_escape'`. Take a specific point, `printf` and `$'C_Style'`
accepts octals not starting with 0, but `echo -e` doesn't.
This is causing quite a lot of confusion.
On older versions of bash, like bash 3.2 on OS X, `echo` doesn't
understand `\e` but `printf` and `$'C_style'` does. I believe this is quite a
aged problem.
Repeat-By:
printf 'printf starts the bold\33[1m\n'; echo $'C escape should end
it\33[0m'; echo -e 'echo -e does nothing but giving crap\33[1;31m'
