hi,
cut -d is unreliable in this case, as the ps output is formatted. so if you have two process ids of different length (i.e., 345, 23456) there will be leading spaces on the shorter one.
instead, use 'cut -c1-5'
then, you have to embed your command in a loop, like this:
the var $each is automatically created. the result of command in backticks is a list over which the for loop iterates.

What is the proper way to run two bash loops in the same command? The two below loops run separately, the problem is when I pipe them I get an error that the file used for the second loop does not exist. I am not sure how to wait for the first loop to complete and then start the second. Thank... (10 Replies)

DESCRIPTION
cut-diff is a diff command that uses diff feature in Cutter. It shows difference with color.
It's recommended that you use a normal diff(1) when you want to use with patch(1) or you don't need color.

cut-diff shows its own version and exits.
-c [yes|true|no|false|auto], --color=[yes|true|no|false|auto]
If 'yes' or 'true' is specified, cut-diff uses colorized output by escape sequence. If 'no' or 'false' is specified, cut-diff never
use colorized output. If 'auto' or the option is omitted, cut-diff uses colorized output if available.
The default is auto.
-u, --unified
cut-diff uses unified diff format.

Shows diff context around LINES.
All lines are shown by default. When unified diff format is used, 3 lines are shown by default.
--label=LABEL, -L=LABEL

asfile2's label.
Labels are the same as file names by default.
EXIT STATUS
The exit status is 0 for success, non-0 otherwise.
TODO: 0 for non-difference, 1 for difference and non-0 for errors.

In the following example, cut-diff shows difference between file1 and file2:
