I intend to copy a number of files chosen from a given directory. At
first, I've made a mistake : instead of deleting unwanted files from a
copy of said directory, I worked on deleting lines on a filelist that I
had extracted
using 'ls -l > filename.txt'.
I am not sure I understand what you trying to do. Neither do I
understand what you did instead. :) If you just edited filename.txt in a
wrong way, whats preventing you from regenerating it?
This sorting job,
Which sorting job? You didn't mention any sorting until now.
on about 12,500 lines,
took several hours of my time,
Whoah! You didn't sort 12,500 lines manually, did you? You could have
just used 'sort'. If your hardware isn't ancient, that shouldn't take
more than a few seconds.
yes, sort sounds valuable :)
and I hope to find a way to make use of
the result obtained, rather than re-doing the whole sorting job. The
sorted files number about 400 or so. Had it been only 2 or 3 dozens of
files, I would not have hesitated repeating the following command for
each file :
cp
/mnt/exthd/home/bd/office52/user/desktop/etc/etc/filename_pasted_from_the_list
/home/mydir
for f in $files; do
cp "/source/$f" /target/
done
strings of characters since they are "subjects" of e-mails received via
StarOffice 5.1 and 5.2.
Ouch. You might have problems with my solution if the subjects contain
weird characters. Spaces shoudl be fine, though.
No, spaces are not fine in your example.
for f in $files <-- the word splitting already occurs here.
You'd need at least:
set -f
OIFS="$IFS"
IFS=$'\n'
for f in $files; do
cp "/source/$f" "/target/"
done
IFS="$OIFS"
set +f
If you want to read from a file and the file already contains the list
of file names (one on each line), then I'd use a `while read` loop.
set -f
while read str_line; do
cp "${str_line}" "/target/"
done < <("${filename}")
set +f
set -f disables file name globbing and should help care about weird
characters in that case.
while read str_line reads a line by default, so no need to set IFS.
