Question

unix command:

If you type the command: apropos keyboard, you'll get both commands and functions. Commands will contain the string (1). Write a command that will output only the command results for apropos keyboard?

Answer 1

command for above mentioned function is :

apropos email | sed 's/|/ /' | awk '{print $1, $2}'

for filtering the results of the apropos command, i am pipelining the apropos with sed command and then pipeling whole with awk command to split the results according to the columns and then i am displaying the first and second columns according to the need.

you can display only first column also just remove '$2' from the command.
