Using svn in a unix pipe
I realize that not all command line commands can be used in a unix pipe.
But it would really help me not only satisfy an itch but help in my
development process if someone here more knowledgeable in unix could give me
a hint.
What I am trying to do is take the output of ³svn st² and pipe that back
into ³svn add² or ³svn del² or...
I have so far got
svn st | egrep ³\?² | sed s/\?\(.*\)/ \1/¹ | svn add
So svn is outputting to egrep which is taking all the files marked ³?² and
sending that to sed to strip off the ³?² (which could be ³!² ..etc) which I
would then like to send to svn add (or delete or...).
Problem is the stdout is not making it to the add argument.
Any help would be appreciated.
Steven

You could change that around, and use back-ticks:
svn add `svn st | egrep “\?” | sed ‘s/\?\(.*\)/ \1/’`

I do not believe "svn add" makes any use of things passed to it via
stdin like that. Rather, it acceps parameters on its command line.
The command "xargs" is useful for converting from the one to the other.

I find sed is simpler, and avoids whitespace issues:
svn st | sed -nr "/^\?/s/.{7}(.*)/'\1'/p" ...

Ah... doh! Ok that's solved by cut:
svn st | grep ^\? | cut -c 6- | tr "\n" "\000" | xargs -0 -n1 svn add
(Jorge previously suggested cut -c 6-500 which truncates at 500 chars)
Like Saulius though I usually resort to a single tool, but for me its
perl not sed:
svn st | perl -ne 'print if s/^\?.{5}(.*)/$1\000/' | xargs -0 -n1 svn add
Saulius' sed script fails when there's apostrophes in the filenames.

The problem is that 'print $2' in awk will only print out the second
field, and by default it splits on whitespace, so if you've got
filenames with spaces $2 is only the first chunk of it, so I suspect
that tr won't help...

try this:
svn st | grep ^\? | awk '{ print $2 }' | tr "\n" "\000" | xargs -0 -n1 svn add
that should work if there's spaces in the filename, but one add at a
time (I'm not sure if you absolutely *need* -n1 if you're using -0,
but I've always stuck to the tricks I know)

I usually use cut for this:
svn add `svn st | grep "^?" | cut c6-500`
I like this contest :-)

The "xargs" was missing in Steven's original pipeline.
But be careful, Steven (and others who may be reading),
because xargs may split your list up and invoke "svn add"
multiple times. Check "man xargs" on your system to see
whether you need to be scared; on mine it'll start splitting
once the command line gets beyond 5k bytes.
If there's any danger that you'll need more than that,
you want "svn add --targets". Unfortunately, that seems
to require a genuine filename:
$ svn add --targets -
svn: Reading from stdin is currently broken, so disabled
so you can't use a pipeline as such any more. Then again,
with a list that long you might be glad of a record of
just what you fed to "svn add" anyway.

I suspect your sed command isn't working, if you drop the | svn add
off the end you'll see that there just isn't any output at that point.
Note that I do something very similar with awk all the time:
svn st | grep ^\? | awk '{ print $2 }' | xargs svn add
And it works just fine (assuming there aren't any spaces in your
filenames anyway).

Re: Using svn in a unix pipe

I think what you want is:
svn add * --force
This will add everyfile with a status of "?"
Also, correct me if I'm wrong, but you can't "svn delete" a file
that's not under version control (i.e. any file with "?" status)
I hope this helps,
Mike

Try
svn st | egrep "^?" | sed 's/\?\(.*\)/ \1/' | xargs -t svn add
or
svn st | egrep "^?" | sed 's/\?\(.*\)/ \1/' | xargs -t -n1 svn add
(to add files one by one)
This will probably do what you want.
I have also a script 'svn-add-unknown' which uses backticks and awk for this
purpose. (I attach my svn scripts to this mail)
