use tee to save log file in a subfolder (defined in a variable)

  • 772

The input file of a script is passed as an argument from command line. I want the log file from tee to be saved in the same directory than the input file:

Lets say that input file is at "data/temp/inputfile.txt"

This is the part that is giving me problems:

{
INPUT1=$1

#Save each subdirectory as an element of the array
bkpIFS="$IFS"
IFS='/' read -r -a inputstring <<< $INPUT1
IFS="$bkpIFS"

#Get number of levels
PATHLENGTH=${#inputstring[@]}

if [ PATHLENGTH > 1 ]
then
    #Delete the input file from path
    FILEONLY=${inputstring[-1]}
    INPUTFOLDER=${INPUT1/%$FILEONLY/}
    #Name the log file
    LOGFILE="arrays.log"
    LOGPATH="$INPUTFOLDER$LOGFILE"
else
    #If input file is at working directory
    LOGPATH="arrays.log"
fi

# Here goes the main script...

printf "\nDone!\n"

}  | tee $LOGPATH

I'm just getting an empty file named "1" at the working directory. Of course if I write in the last line:

} | tee arrays.log

everything goes well, but I need each log file in the same place than the input file.

log bash tee

    Looks overly complicated. 

    LOGPATH=$(dirname $1)/arrays.log

    should do the same thing, even in the case where there is no directory in $1 (because $dirname foobar returns .).
