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!

sim, SIM - Software phrase input method
DESCRIPTION
The phrase input method is an input method that is commonly used in a Chinese environment. The software phrase input method (SIM) is a a
mechanism supported by the Asian tty driver, atty and the simd daemon through the utx facility (see atty(7), simd(8), and utx(7)).
The stty command activates the software phrase input method, while the phrase utility creates and manages the phrase database (see stty(1)
and phrase(1)).
Changes to the phrase database may not be reflected in SIM sessions that were started before the changes were made. Therefore, users have
to stop and then restart SIM sessions using the stty command to have access to the changed phrase database.
