Hi, i've got the following:
a=`echo $b | grep '^.*/'`
i'm storing in the variable the value of the variable b only if it has a / somewhere.
It works, but i don't want to print the value. How do i give the value of b to the grep command without the echo?
thanks! (5 Replies)
I am performing a grep command and I need to know how to echo "NONE" or "0" to my file if grep does not find what i am looking for.
echo What i found >> My_File
grep "SOMETHING" >> My_File
I am sure this is easy, I am sort of new at this!
Thanks (2 Replies)

-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

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.

The exit status is 0 for success, non-0 otherwise.
TODO: 0 for non-difference, 1 for difference and non-0 for errors.
