linux - [Solved-5 Solutions] Iterate over a list of files with spaces - ubuntu - red hat - debian - linux server - linux pc
Linux - Problem :
If you need to iterate over a list of files. This list is the result of a find command
getlist() {
for f in $(find . -iname "wiki*")
do
echo "File found: $f"
# do something useful
done

It's fine but if a file has spaces in its name:
$ ls
wiki_bar_baz.txt
wiki bar baz.txt
$ getlist
File found: wiki_bar_baz.txt
File found: wiki
File found: bar
File found: baz.txtclick below button to copy the code. By - Linux tutorial - team

Linux - Solution 2:
It handles Spaces :
OIFS="$IFS"
IFS=$'\n'
for file in `find . -type f -name "*.csv"`
do
echo "file = $file"
diff "$file" "/some/other/path/$file"
read line
done
IFS="$OIFS"click below button to copy the code. By - Linux tutorial - team
It handles wildcards and newlines in file names:
find . -type f -name "*.csv" -print0 | while IFS= read -r -d '' file; do
echo "file = $file"
diff "$file" "/some/other/path/$file"
read line </dev/tty

You can use this :
find . -type f -name '*.csv' -exec sh -c '
file="$0"
echo "$file"
diff "$file" "/some/other/path/$file"
read line </dev/tty

Linux - Solution 3:
$ mkdir test
$ cd test
$ touch "wikitechy file1"
$ touch "wikitechy file2"
$ touch "wikitechy file 3"
$ ls
wikitechy file 3 wikitechy file1 wikitechy file2
$ for file in *; do echo "file: '${file}'"; done
file: 'wikitechy file 3'
file: 'wikitechy file1'
