I'm trying to run
watch, so that it shows me the output from my grep command, while I am running over files and changing things.
The usual way of doing this works fine, but lacks colors:
watch grep 'something' **/*
...and since I do want colors, I did this:
watch grep 'something' **/* --color=always
It's still ugly, because watch doesn't parse the escape codes that make the colors work. So then I found this:
watch --color grep 'something' **/* --color=always
And well... it doesn't work. The output is fragmented / mixed up in some weird way. It shows me only a single line for some reason, while without
watch --color the grep outputs about 20.
How can I make
watch work with colorized output from
Using the following:
mkdir grep_test; cd grep_test echo "asdsad\nasdasd\nsaasdasd" > file1 echo "test\n123\ntest" > file2
I create two files, and run the following command:
grep test * --color=always
Which works as expected, and outputs (with colors and whatnot):
But when I use watch:
watch --color 'grep test * --color=always'
It outputs nothing. Without the
--color option it shows the right output, though without the ANSI escapes interpreted.
I'm running this on Fedora 25, in tmux session with zsh inside.
watch -v output is:
watch from procps-ng 3.3.10
