Almost all of the subcommands of CVS work recursively when you specify a directory as an argument. For instance, consider this directory structure:
$HOME
|
+--tc
| |
+--CVS
| (internal CVS files)
+--Makefile
+--backend.c
+--driver.c
+--frontend.c
+--parser.c
+--man
| |
| +--CVS
| | (internal CVS files)
| +--tc.1
|
+--testing
|
+--CVS
| (internal CVS files)
+--testpgm.t
+--test2.t
If `tc' is the current working directory, the following is true:
cvs update testing/testpgm.t testing/test2.t
tc
directory
If no arguments are given to update
it will
update all files in the current working directory and
all its subdirectories. In other words, `.' is a
default argument to update
. This is also true
for most of the CVS subcommands, not only the
update
command.
The recursive behavior of the CVS subcommands can be turned off with the `-l' option. Conversely, the `-R' option can be used to force recursion if `-l' is specified in `~/.cvsrc' (see section Default options and the ~/.cvsrc file).
$ cvs update -l # Don't update files in subdirectories
