I need to log theoutput of utilities in a way that I always know its version,
forwhich I have been using a file with lines of text, each linecontaining 5
fields with all you need:
<installationprogram>|<utility>|<version option>|<on whichline>|<which string
on that line>
texlive-extra-utils|pdfcrop|--version|1|3
pdftotext|pdftotext|-v|1|3
kate|kate|--version|1|2
yt-dlp|yt-dlp|--version|1|2
but I don't know howto inset the last (fifth) field into the awk part of the
statement toget the version:
IFS=$(echo -en"\n\b"); _L_AR=($( echo "${_L}" | tr '|'
'\n'));_L_ARL=${#_L_AR[@]}
if [[ ${_L_ARL} -eq5 ]]; then
_UTIL="${_L_AR[1]}"
#
which "${_UTIL}"
"${_UTIL}"${_L_AR[2]} 2>&1 | head -n ${_L_AR[3]}
# _V=${_L_AR[4]};"${_UTIL}" ${_L_AR[2]} 2>&1 | head -n ${_L_AR[3]} |awk '{print
$'${_V}'}' # can't get the version ..
else
echo "// __\$_L: |${_L}|, \$_L_ARL: |$_L_ARL|"
fi
