hi everyone

a good basher around here?

I try in a script:

_rdiffBack=”rdiff-backup -v5 –tempdir /tmp/ –no-eas
–exclude-other-filesystems –exclude-symbolic-links”
_rdffiExclude=”–exclude ‘**/~*’ –exclude ‘**.tmp’
–exclude-regexp ‘(.glusterfs|.trashcan|temp)'”
_execCom=${!2}
_sourceDir=${1}
_backupTo=${3}

__backMeUp() {
for _sourceDir in ${_sourceDirs[@]}; do
echo \$ ${_execCom} ${_rdffiExclude} ${_sourceDir}/
${_backupTo} \> ${_logFile} | ${_copyToLog}
${_execCom} ${_rdffiExclude} ${_sourceDir}/
${_backupTo} > ${_logFile} 2>&1
done
}

case ${1} in
rdiffThis)
declare -a _sourceDirs=( /0-ALL.DATA/rdiffThis );
__backMeUp ${@}
;;
esac

this is a snippet which may look obscure but obvious is:
rdiff-backup some data, just that. And when I run it as a script

~]$ runme.sh rdiffThis _rdiffBack toHere

I see:
Fatal Error: Fatal Error: The file specification
”**’
cannot match any files in the base directory

You notice that the script echos what it is meant to execute, which suffice I copy&paste that echo in bash prompt… and it works!? No “Fatal Error”
And the problem seems to specifically be a shell pattern for
–exclude. Take two –exclude out, having:

_rdffiExclude=”–exclude-regexp ‘(.glusterfs|.trashcan|temp)'”

and script works when invoked, fine!
I’ve been fiddling around but failed to make rdiff-backup
1.2.8 play along. Must be something trivial, right?
b.w. L
