 |
|
I have searched high and low (but probably not high or low enough) for this but can't find a solution:
How do I remove "colored output"?
This is an example of what I mean:
| Code: | [01mHP Linux Imaging and Printing System (ver. 2.8.6b)[0m
[01mSupply Levels Utility ver. 1.3[0m
[01mUsing device: hp:/usb/deskjet_5600?serial=HU3791Y0HR89[0m
[01mBlack cartridge[0m
Part No.: 56 (C6656A)
Health: Very low
[01m |
How do I remove the [01m things from my output? I want to email it with a script but this looks really messy now. I tried several things, including parsing it trough unix2dos and dos2unix but to no avail... Hope you gurus out here can help me  |

v1pEr,
Try the option --color=never on commands. Some understand it.
Also read /etc/bash/bashrc where you can set colour off for all your shells.
Its --color not --colour
Piping command output to a file drops the ANSI colour sequences too.

Strange, on my box it doesn't, except the following is not what you meant:
| Code: | RoSe v1per # hp-levels > /tmp/hp-levels && cat -v /tmp/hp-levels
^[[01mHP Linux Imaging and Printing System (ver. 2.8.6b)^[[0m
^[[01mSupply Levels Utility ver. 1.3^[[0m |
Thank you for the thread eccerr0r! Following script works PERFECTLY!
| Code: | #!/usr/bin/perl
# StripANSI .. remove ANSI codes from stdin
# Also removes removes backspace bolds and BitchX IRC ^B's
while(<>){s/\e\[[\d;]*.//g;s/(.)\cH\1/$1/g;s/\cB//g;print;} |

That depends on the application (most programs will check if stdout is a tty and disable colors if it isn't). |

And if that would have been the case, I wouldn't have needed the script in the first place |
