First...
DO NOT USE CSH FOR SCRIPTS. Use /bin/sh. (And I use tcsh for my
interactive shells, wouldn't dream of writing scripts in it.)
#!/bin/sh
#
if mv $* ~/tmp; then
echo "The files have been moved! To remove them "
echo "use the 'purge' command "
else
echo "Something's haywire! Files not moved. "
fi
Second, if some evil force is compelling you to use csh, RTFM, csh(1),
Expressions
Several of the builtin commands (to be described later) take expressions,
in which the operators are similar to those of C, with the same prece-
dence. These expressions appear in the @, exit, if, and while commands.
.
.
.
Also available in expressions as primitive operands are command execu-
tions enclosed in `{' and `}'...
So, if you were actually to use csh, you want,
#!/bin/csh
#
if { mv $* ~/tmp } then
echo "The files have been moved! To remove them "
echo "use the 'purge' command "
else
echo "Something's haywire! Files not moved. "
endif
