.SH NAME
|
||
|
|
descend \- walk directory tree and execute a command at each node
|
||
|
|
.SH SYNOPSIS
|
||
|
|
.B descend
|
||
|
|
[
|
||
|
|
.B \-afqrv
|
||
|
|
]
|

|
|
.I command
|
||
|
|
[

|

|
|
.SH DESCRIPTION
|
||
|
|
.B descend
|
||
|
|
walks down a directory tree and executes a command at each node. It
|
||
|
|
is not as versatile as
|
||
|
|
.BR find (1),
|
||
|
|
but it has a simpler syntax. If no
|
||
|
|
.I directory
|
||
|
|
is specified,
|
||
|
|
.B descend
|
||
|
|
starts at the current one.
|
||
|
|
.LP
|
||
|
|
Unlike
|
||
|
|
.BR find ,
|
||
|
|
.B descend
|
||
|
|
can be told to skip the special directories associated with RCS,
|
||
|
|
CVS, and SCCS. This makes
|
||
|
|
.B descend
|
||
|
|
especially handy for use with these packages. It can be used with
|
||
|
|
other commands too, of course.
|
||
|
|
.LP
|
||
|
|
.B descend
|
||
|
|
is a poor man's way to make any command recursive. Note:
|
||
|
|
.B descend
|
||
|
|
does not follow symbolic links to directories unless they are
|
||
|
|
specified on the command line.
|
||
|
|
.SH OPTIONS
|
||
|
|
.TP 15
|
||
|
|
.B \-a
|
||
|
|
.I All.
|
||
|
|
Descend into directories that begin with '.'.
|
||
|
|
.TP
|
||
|
|
.B \-f
|
||
|
|
.I Force.
|
||
|
|
Ignore errors during descent. Normally,
|
||
|
|
.B descend
|
||
|
|
quits when an error occurs.
|
||
|
|
.TP
|
||
|
|
.B \-q
|
||
|
|
.I Quiet.
|
||
|
|
Suppress the message `In directory
|
||
|
|
.IR directory '
|
||
|
|
that is normally printed during the descent.
|
||
|
|
.TP
|
||
|
|
.B \-r
|
||
|
|
.I Restricted.
|
||
|
|
Don't descend into the special directories
|
||
|
|
.SB RCS,
|
||
|
|
.SB CVS,
|
||
|
|
.SB CVS.adm,
|
||
|
|
and
|
||
|
|
.SB SCCS.
|
||
|
|
.TP
|
||
|
|
.B \-v
|
||
|
|
.I Verbose.
|
||
|
|
Print
|
||
|
|
.I command
|
||
|
|
before executing it.
|
||
|
|
.SH EXAMPLES
|
||
|
|
.TP 15
|
||
|
|
.B "descend ls"
|
||
|
|
Cheap substitute for `ls -R'.
|
||
|
|
.TP 15
|
||
|
|
.B "descend -f 'rm *' tree"
|
||
|
|
Strip `tree' of its leaves. This command descends the `tree'
|
||
|
|
directory, removing all regular files. Since
|
||
|
|
.BR rm (1)
|
||
|
|
does not remove directories, this command leaves the directory
|
||
|
|
structure of `tree' intact, but denuded. The
|
||
|
|
.B \-f
|
||
|
|
option is required to keep
|
||
|
|
.B descend
|
||
|
|
from quitting. You could use `rm \-f' instead.
|
||
|
|
.TP
|
||
|
|
.B "descend -r 'co RCS/*'" /project/src/
|
||
|
|
Check out every RCS file under the directory
|
||
|
|
.BR "/project/src" .
|
||
|
|
.TP
|
||
|
|
.B "descend -r 'cvs diff'"
|
||
|
|
Perform CVS `diff' operation on every directory below (and including)
|
||
|
|
the current one.
|
||
|
|
.SH DIAGNOSTICS
|
||
|
|
Returns 1 if errors occur (and the
|
||
|
|
.B \-f
|
||
|
|
option is not used). Otherwise returns 0.

.SH BUGS
|
||
|
|
Shell metacharacters in
|
||
|
|
.I command
|
||
|
|
may have bizarre effects. In particular, compound commands
|
||
|
|
(containing ';', '[', and ']' characters) will not work. It is best
|
||
|
|
to enclose complicated commands in single quotes \(aa\ \(aa.
