Basic phonebook via BASH
I’d like to write about the super cool bash
technique I learned from a
training video of 2011.
Yes, you can implement super basic phonebook application via shell script.
Create a file called: phonebook
# phonebook
#!/usr/bin/env bash
# name phone-number
# name phone-number
# name phone-number
# name phone-number
grep -i $* <<EOF
vigo 0123-456-78-99
jack 0123-456-78-99
max 0123-456-78-99
turbo 0123-456-78-99
EOF
then make it executable: chmod +x phonebook
. Now make query!
$ ./phonebook vigo
vigo 0123-456-78-99
