Synopsis
- sh·ell | ! [ command [ arg ... ] ]
Description
The shell command creates a subshell.
UNIX® and Linux® — view context
The subshell is created with the same view context as the current process. If the current process is set to one view, but the working directory view is different, shell uses the working directory view. (For more information, see the pwv reference page.)
The shell command is intended for use in cleartool and multitool interactive mode. If you are using single-command mode, there is no need for this command.
Restrictions
None.
Options and arguments
Program to run in subprocess
- Default
- Runs the shell program indicated by your SHELL (UNIX® and Linux®) or ComSpec
(Windows®)
environment variable (or /bin/sh (UNIX® and Linux®) or cmd.exe (Windows®),
if your environment does not include SHELL/ComSpec). The shell runs interactively
until you exit from it. Note: On Windows®, changing the ComSpec variable to a value other than cmd.exe may have undesirable side effects elsewhere in your work environment. To avoid this problem, you can invoke the alternative shell explicitly from cmd.exe, after executing shell.
- command [ arg ... ]
- Runs a noninteractive shell which, in turn, invokes the program command, (and, optionally, passes it one or more arguments). The subshell exits immediately after executing command.
Examples
UNIX® and Linux®
- Create a subshell that is set to the same
view as the cleartool process.
cleartool> shell
- Create a subshell, and run a command within
it.
% ! head -2 /etc/passwd
sysadm:*:0:0:System V Administration:/usr/admin:/bin/sh
diag:*:0:996:Hardware Diagnostics:/usr/diags:/bin/csh
Windows®
- Create an interactive subshell, and then
run a dir command in that shell.
cleartool shell
> dir *.c
...
> exit - Create an noninteractive subshell that runs
a dir command.
cleartool shell dir *.c
...
