I need to log the
output of utilities in a way that I always know its version, for
which I have been using a file with lines of text, each line
containing 5 fields with all you need:
<installation
program>|<utility>|<version option>|<on which
line>|<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 how
to inset the last (fifth) field into the awk part of the statement to
get the version:
IFS=$(echo -en
"\n\b"); _L_AR=($( echo "${_L}" | tr '|' '\n'));
_L_ARL=${#_L_AR[@]}
if [[ ${_L_ARL} -eq
5 ]]; then
_UTIL="${_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
