KSH ( 1 ) KSH(l)
if any. If n is specified then break n levels.
continue [ n ]
Resume the next iteration of the enclosing for, while,
until, or select loop. If n is specified then resume at the
nth enclosing loop.
cd [ arg ]
cd old new
This command can be in either of two forms. In the first
form it changes the current directory to arg . If arg is -
the directory is changed to the previous directory. The
shell parameter HOME is the default arg . The parameter
PWD is set to the current directory. The shell
parameter CDP ATH defines the search path for the
directory containing arg . Alternative directory names are
separated by a colon (:). The default path is
(specifying the current directory). Note that the current
directory is specified by a null path name, which can
appear immediately after the equal sign or between the
colon delimiters anywhere else in the path list. If arg
begins with a / then the search path is not used. Otherwise,
each directory in the path is searched for arg.
The second form of cd substitutes the string new for the
string old in the current directory name, PWD, and tries
to change to this new directory.
eval [ arg ••• ]
The arguments are read as input to the shell and the
resulting command(s) executed.
exec [ arg ••• ]
Parameter assignments remain in effect after the command
completes. If arg is given, the command specified
by the arguments is executed in place of this shell without
creating a new process. Input/output arguments may
appear and affect the current process. If no arguments are
given the effect of this command is to modify file descriptors
as prescribed by the input/output redirection list. In
this case, any file descriptor numbers greater than 2 that
are opened with this mechanism are closed when invoking
another program.
exit [ n]
Causes the shell to exit with the exit status specified by n.
If n is omitted then the exit status is that of the last command
executed. An end-of-file will also cause the shell to
exit except for a shell which has the ignoreeof option (see
set below) turned on.
export [ name ••• ]
The given names are marked for automatic export to the
environment of subsequently-executed commands.
