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:
Code:
for each in `command`;do kill -9 $each;done

the var $each is automatically created. the result of command in backticks is a list over which the for loop iterates.

hth,
dv

NAME
cut-diff - show difference between 2 files with color SYNOPSIS
cut-diff [option ...] file1 file2 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. OPTIONS
--version 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. --context-lines=LINES 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 Uses LABEL as a header label. The first--label option value is used as file1's label and the second --label option value is used 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. EXAMPLE
In the following example, cut-diff shows difference between file1 and file2: % cut-diff file1 file2 In the following example, cut-diff shows difference between file1 and file2 with unified diff format: % cut-diff -u file1 file2 SEE ALSO
