Getting number of different files

Up a Level

since we are using $ to get the PID of the process.

rm -f /tmp/convert-status-$

Figure out the width of the files. We do this so the columns line up

pretty and has absolutely no impact on the functionality.

for dir in “$@” do # Ignore non-directories. if [ ! -d “$dir” ] then # Create a generic placeholder for all non-directories. echo “-FILES-” >> /tmp/convert-status-$ continue fi

# Include the directory name.
echo "$dir" >> /tmp/convert-status-$

done

This fancy little bit of AWK (which is from the Internet and I don't

exactly grok) figures out the maximum length string in the file we

just created. After this run, $m will contain the longest string

length (as an integer).

m=$(awk ' { if ( length > L ) }END' /tmp/convert-status-$)

Keep track of all the totals. We use `printf` even though we could

use `echo` just so all the output calls are identical.

printf “%-$s Count MP4 MKV AVI MOV MPG\n” printf “%-$s —– —- —- —- —- —-\n”

These are the counters for the grand totals (max) and the

non-directory counts (files).

max=0 max_mkv=0 max_mp4=0 max_avi=0 max_mov=0 max_mpg=0

files=0 files_mkv=0 files_mp4=0 files_avi=0 files_mov=0 files_mpg=0

Go through a list of all the directories in the parameters.

for dir in “$@” do # Ignore non-directories. if [ ! -d “$dir” ] then # If this is a file, we just add to the counters. case ${dir#*.} in “mp4”) files_mp4=$(expr $files_mp4 + 1);; “mkv”) files_mkv=$(expr $files_mkv + 1);; “avi”) files_avi=$(expr $files_avi + 1);; “mov”) files_mov=$(expr $files_mov + 1);; “mpg”) files_mpg=$(expr $files_mpg + 1);; *) continue;; esac

    # Increment the general file counter.
    files=$(expr $files + 1)

    # Don't bother doing anything else.
    continue
fi

# Count the number of files of a given type inside that
# directory. Since we are using `find`, this will recursively get
# all the files inside subdirectories also. We don't care about
# the file names, just how many we find. This does have a slight
# bug if you have a .filename.extension file (which I use for
# temporary files), but usually that is okay.
mkv=$(find "$dir" -name "*.mkv" | wc -l)
mp4=$(find "$dir" -name "*.mp4" | wc -l)
avi=$(find "$dir" -name "*.avi" | wc -l)
mov=$(find "$dir" -name "*.mov" | wc -l)
mpg=$(find "$dir" -name "*.mpg" | wc -l)

# Add up all the counts above so we have a "total files per
# directory" variable.
count=$(expr $mkv + $mp4 + $avi + $mov + $mpg)

# Increment the grand totals for the bottom line.
max_mp4=$(expr $max_mp4 + $mp4)
max_mkv=$(expr $max_mkv + $mkv)
max_avi=$(expr $max_avi + $avi)
max_mov=$(expr $max_mov + $mov)
max_mpg=$(expr $max_mpg + $mpg)
max=$(expr $max + $count)

# Write out a single record for everything, but only if we have
# something.
if [ $count -gt 0 ]
then
    printf "%-${m}s  %5d %4d %4d %4d %4d %4d\n" \
        "$dir" \
        $count $mp4 $mkv $avi $mov $mpg
fi

Write out the file totals, but only if we have at least one file.

if [ $files -gt 0 ] then printf “%-$s %5d %4d %4d %4d %4d %4d\n”

“-FILES-”

$files $files_mp4 $files_mkv $files_avi $files_mov $files_mpg fi

Write out the grand totals.
