Release Status: release
Description:
# Just that the following commands (when pasted to command-line) can be
easier read...
clear
#
# Imagine the folder '/tmp/bla' whith the follwowing contest:
# 2 files named: "a aaaaa aaa.mp3" and "c - c.mp3"
# (
mkdir /tmp/bla; touch "/tmp/bla/a aaaaa aaa.mp3";
touch "/tmp/bla/c - c.mp3"
# )
#
# Now try to process all these files in a bash-script with the following
commands:
#
for a in `find /tmp/bla -iname "*.mp3" -printf "\"%f\" "`; do
echo "'$a'"; done
#
# It gives you:
# '"a'
# 'aaaaa'
# 'aaa.mp3"'
# '"c'
# '-'
# 'c.mp3"'
#
# But I think it SHOULD BE:
# 'a aaaaa aaa.mp3'
# 'c - c.mp3'
#
# Because:
tmp=`find /tmp/bla -iname "*.mp3" -printf "\"%p\""`;
echo "tmp='$tmp'"
# gives you:
# tmp='"a aaaaa aaa.mp3" "c - c.mp3"'
# And:
for a in "a aaaaa aaa.mp3" "c - c.mp3"; do echo
"'$a'"; done
# gives you:
# 'a aaaaa aaa.mp3'
# 'c - c.mp3'
#
# And to clear it up at finish:
rm -R /tmp/bla

#
# Is this a bug or a feature?
#
# Or (if it's NOT a bug): How is it possible to get the "SHOULD
BE"-result ???
# (Help would be VERY APRECIATED! - although I KNOW, that this is NOT the
bash-help-line!
# - because I really think this is/should-be a bug...)
#
#
# If it is NOT a bug, then please give me at least a short remark on that!
# ( email: Posern@stud-mailer.uni-marburg.de )
# This would be nice.
#
# Thanks right now!

# Greetings
