I currently have the following shell command which is only partially working:
svn list $myrepo/libs/ |
xargs -P 10 -L 1 -I {} echo $myrepo/libs/ {} trunk |
sed 's/ //g' |
xargs -P 20 -L 1 svn list --depth infinity |
grep .xlsx
where $myrepo corresponds to the svn server address.
The libs folder contains a number of subfolders (currently about 30 although eventually up to 100), each which contain a number of tags, branches and a trunk. I wish to get a list of xlsx files contained only within the trunk folder of each of these subfolders. The command above works fine however it only returns the relative path from $myrepo/libs/subfolder/trunk/, so I get this back:
1/2/3/file.xlsx
Because of the potentially large number of files I would have to search through, I am performing it in two parallel steps by using xargs -P (I do not have and cannot use parallels). It am also trying to do this in one command so it can be used in php/perl/etc. and avoid multiple sytem calls.
What I would like to do is concatenate the input to this part of the command:
xargs -P 20 -L 1 svn list --depth infinity
with the output from it, to give the following:
$myrepo/libs/subfolder/trunk/1/2/3/file.xlsx
Then pass this to the grep to find the xlsx files.
I appreciate any assistance that could be provided.
If I manage to correctly divine your intention, something like this might work for you.
svn list "$myrepo/libs/" |
xargs -P 20 -n 1 sh -c 'svn list -R "$0/trunk/$1" |
sed -n "s%.*\.xlsx$%$0/trunk/$1/&%p"' "$myrepo"
Briefly, we postprocess the output from the inner svn list to filter to just .xslx files and tack the full SVN path back on at the same time. This way, the processing happens where the repo path is still known.
We hack things a bit by passing in "$myrepo" as "$0" to the subordinate sh so we don't have to export this variable. The input from the outer svn list comes as $1.
(The repos I have access to have a slightly different layout so there could be a copy/paste error somewhere.)
