Find files and tar them with trailing or leading space in their name

Question

I have a script, that tries to archive the contents of a directory with tar:

#!/bin/bash

find /root/files -type f -name "1*" -print0 | while read -d $'\0' file
do
    MYDIRNAME=$(dirname "${file}")
    MYFILENAME=$(basename "${file}")
    MYMODIFYDIR=$(echo "$MYDIRNAME" | sed 's/^\///' | sed 's/\//_/g' | sed 's/\ /_/g')
    MYMODIFYFILENAME=$(echo "$MYFILENAME" | sed 's/\//_/g' | sed 's/\ /_/g')
    GZIP=-9 tar -zcvf /root/"$MYMODIFYDIR"_"$MYMODIFYFILENAME".tar.gz "$file"
done

It does not work with files that have leading or trailing whitespace in their name. The error happens when reaching the file /root/files/tetst\ test\ tgdjd/1\ 5765765\ 565765\ (note the trailing whitespace in the filename):

tar: /root/files/tetst test tgdjd/1 5765765 565765: Cannot stat: No such file or directory
tar: Exiting with failure status due to previous errors

The error given by tar has the trailing whitespace trimmed from the filename.

you could always run `tar` command with `.tar.gz` extension & then rename the file using `mv`. — anishsane, May 13 '15 at 12:10
The problem was that the file contains 1 5765765 565765 space at the end. — Simon482, May 13 '15 at 12:46
And the `/root/files/tetst test tgdjd/1 5765765 565765` file exists? — Etan Reisner, May 13 '15 at 13:01

You can try this:

tar -zcvPf /root/"$MYMODIFYDIR"_"$MYMODIFYFILENAME".tar.gz "$file"

Use the -P option to disable this feature.

You forgot to reset IFS in the while loop, so the leading and trailing whitespaces gets treated as delimiter. Use this:

find /root/files -type f -name "1*" -print0 | while IFS= read -d $'\0' file

You could also add -r to read if there can be backslashes in the filenames.

See here for a more thourough explanation on read and IFS: https://stackoverflow.com/a/26480210/1262699
