Shell not processing color escape codes

Shell not processing color escape codes

[Moore, Thomas (FtWorth)]

[-- Attachment #1: Type: text/plain, Size: 438 bytes --]

Hello,

In my image, I've included systemd. I've noticed that when running the systemctl command, the shell (/bin/sh) is not processing the color escape codes. Here's an example of what it looks like:

[[1;39m82 loaded units listed.[[0m Pass -all to see loaded but inactive units, too.

Any suggestions on how I can either get the shell to process the escape codes or prevent systemctl from generating them?

Thanks,

Thomas

1. Install 'less'
2. append '--no-pager' to commands

There's related a bug on bugzilla.

I added less to my IMAGE_INSTALL, but it looks like I still have the busybox version in my image. How might I go about forcing the use of the standard less?

That's a little strange. The `less' command you are using should be from 
the less package.
It has higher priority than that from busybox.

ALTERNATIVE_${PN} = "less"
ALTERNATIVE_PRIORITY = "100"

The priority from busybox is "50".

Oops. I was running an older version of the image. The new version of the image does have the GNU less command and it works as expected.

Thanks,
