Whilst I have been using BASH for several years, my experience with BASH scripting is relatively limited.
My code is as below. It should grab the entire directory structure from within the current directory and replicate it into $OUTDIR
.
for DIR in `find . -type d -printf "\"%P\"\040"`
do
echo mkdir -p \"${OUTPATH}${DIR}\" # Using echo for debug; working script will simply execute mkdir
echo Created $DIR
done
The problem is, here is a sample of my file structure:
$ ls
Expect The Impossible-Stellar Kart
Five Iron Frenzy - Cheeses...
Five Score and Seven Years Ago-Relient K
Hello-After Edmund
I Will Go-Starfield
Learning to Breathe-Switchfoot
MMHMM-Relient K
Note the spaces :-S And for
takes parameters word by word, so my script's output looks something like this:
Creating directory structure...
mkdir -p "/myfiles/multimedia/samjmusicmp3test/Learning"
Created Learning
mkdir -p "/myfiles/multimedia/samjmusicmp3test/to"
Created to
mkdir -p "/myfiles/multimedia/samjmusicmp3test/Breathe-Switchfoot"
Created Breathe-Switchfoot
But I need it to grab whole filenames (one line at a time) from the output of find
. I have also tried making find
put double-quotes around each filename. But this doesn't help.
for DIR in `find . -type d -printf "\"%P\"\040"`
And output with this changed line:
Creating directory structure...
mkdir -p "/myfiles/multimedia/samjmusicmp3test/"""
Created ""
mkdir -p "/myfiles/multimedia/samjmusicmp3test/"Learning"
Created "Learning
mkdir -p "/myfiles/multimedia/samjmusicmp3test/to"
Created to
mkdir -p "/myfiles/multimedia/samjmusicmp3test/Breathe-Switchfoot""
Created Breathe-Switchfoot"
Now, I need some way that I can iterate through like this, because I also wish to run a more complicated command involving gstreamer
on each file in a following similar structure. How should I be doing this?
Edit: I need a code structure which will allow me to run multiple lines of code for each directory/file/loop. Sorry if I was unclear.
Solution: I initially tried:
find . -type d | while read DIR
do
mkdir -p "${OUTPATH}${DIR}"
echo Created $DIR
done
This worked fine for the most part. However, I later found that since the pipe results in the while loop running in a subshell, any variables set in the loop were later unavailable which made implementing an error counter quite difficult. My final solution (from this answer on SO):
while read DIR
do
mkdir -p "${OUTPATH}${DIR}"
echo Created $DIR
done < <(find . -type d)
This later allowed me to conditionally increment variables within the loop which would remain available later in the script.
/
and unprintable chars. But anything is allowed except/
and\0
so you must allow them.
