227How can I create shorthand versions of long or complex commands on the Unix system?
The commands described below need to be entered while logged in to the Unix server. Normally you'll see a prompt ending with $ when the command interpreter (or shell) is ready for another command.
Use the alias command.
For example, if you put the following line in your .bashrc file:
alias lt='ls -lt|head'
then next time you log in, the command
lt
will list the 10 most recently changed files: The command ls -lt lists files in long format; the | symbol causes the output from ls -lt to be piped into the head command, which itself shows (by default) the first 10 lines of the data received.
