Aliases
QNX SDP8.0User's GuideUser
You can define an alias in the shell to create new commands or to specify your favorite options.
For example, the -F option to the ls
command displays
certain characters at the end of the names to indicate that the file is
executable, a link, a directory, and so on.
If you always want ls to use this option, create an alias:
alias ls='ls -F'
If you ever want to invoke the generic ls command, specify the
path to the executable, or put a backslash (\
) in front of the
command (e.g., \ls).
Aliases are expanded in place, so you can't put an argument into the
middle of the expanded form; if you want to do that, use a shell function
instead.
For example, if you want a version of the cd command that tells
you where you end up in, type something like the following in ksh:
function my_cd
{
cd $1
pwd
}
For more information, see
Functions
in the entry for ksh in the Utilities Reference.
For information on adding an alias or shell function to your profile so
that it's always in effect, see
ksh's startup file
in Configuring Your Environment.
