Copy all svn:* properties from one file to another

pvdb (Peter Vandenberk) — Fri, 16 May 2008 11:25:10 GMT

The following script can be used to copy all SVN properties from one file (presumably a file that's already under SVN control) to another file (which you presumably want to put under SVN control, and which you want to check in with the same SVN properties).



#!/bin/sh



ORIG=$1 ; shift ;

[ -e "$ORIG" ] || exit ;



for PROP in `svn pl "$ORIG" | sed -n '2,$p'` ; do

        VALUE=`svn pg $PROP "$ORIG"` ;

        for FILE ; do

                [ -e "$FILE" ] && svn ps $PROP "$VALUE" "$FILE" ;

        done

done



# That's it, Folks!

If you put the above code in a shell script called...



svnprops.sh

... then you can run it as follows if you want to copy all svn:* properties FROM original.file TO blegga:



pvdb@localhost ~ $ ./svnprops.sh original.file blegga 

property 'svn:mime-type' set on 'blegga'

property 'svn:eol-style' set on 'blegga'

pvdb@localhost ~ $ _

... or as follows for multiple target files:



pvdb@localhost ~ $ ./svnprops.sh another.original.file blegga foo bar 

property 'svn:mime-type' set on 'blegga'

property 'svn:mime-type' set on 'foo'

property 'svn:mime-type' set on 'bar'

pvdb@localhost ~ $ _

substitution for 'ps -aux | grep [P]ROCESS'

as we know, invoking grep after ps with first letter of the PROCESS enclosed in brackets [] (like this: ps -aux | grep [P]ROCESS), excludes grep PROCESS from the output. so, instead of typing those brackets manualy every time, we may use the code below:



FIRST=`echo $1 | sed -e 's/^\(.\).*/\1/'`

REST=`echo $1 | sed -e 's/^.\(.*\)/\1/'`

ps -aux | grep "[$FIRST]$REST"

you may use it as separate shell-script -- like this:



#!/bin/sh

FIRST=`echo $1 | sed -e 's/^\(.\).*/\1/'`

REST=`echo $1 | sed -e 's/^.\(.*\)/\1/'`

ps -aux | grep -v "full/path/to/your/script" | grep "[$FIRST]$REST"

or just include it in your .bashrc or similar -- like this:



function psg

{

FIRST=`echo $1 | sed -e 's/^\(.\).*/\1/'`

REST=`echo $1 | sed -e 's/^.\(.*\)/\1/'`

ps -aux | grep "[$FIRST]$REST"

}
