This strips leading and trailing whitespace.
$ touch " test1"
$ touch "test2 "
$ touch "test 3"
$ touch " test 4 "
$ ls -1 | while read i; do echo "###${i}###"; done
###test2###
###test 3###
###test1###
###test 4###
instead use:
$ ls -1 | while IFS= read i; do echo "###${i}###"; done
###test2 ###
###test 3###
### test1###
### test 4 ###
or recursively:
$ find . -type f -print0 \
| while IFS= read -d $'\0' i; do echo "###${i}###"; done
###./ test1###
###./ test 4 ###
###./test 3###
###./test2 ###
or just make things simple on yourself :)
$ for i in *; do echo "###${i}###"; done
### test1###
###test2 ###
###test 3###
### test 4 ###
