NAME

SYNOPSIS

DESCRIPTION

With no arguments, a subshell is created. If the environment variable SHELL or shell is set to, for instance, /bin/sh or /bin/csh, that shell will be used. If the environment variable is not set, the default /bin/sh will be used.

If a command string is entered after the u, /bin/sh is run to execute that single line, and the return to C-PLOT is immediate.

Don't try to change directory using u cd direc. This command will only change the directory of the subshell. The subshell disappears as soon as it has changed its directory and has no effect on the plot program. Use the cd command to change the current directory within C-PLOT.
