Bash Shell list files using "for" loop
If you're using bash 4, just use a glob:
#!/bin/bash shopt -s globstarfor file in **/*.txtdo if [[ ! -f "$file" ]] then continue fi echo "$file" # Do something else. doneBe sure to quote "$file" or you'll have the same problem elsewhere. ** will recursively match files and directories if you have enabled globstar.
Yes, have find separate the file names with NUL and use read to delimit on NUL. This will successfully iterate over any file name since NUL is not a valid character for a file name.
#!/bin/bashwhile IFS= read -r -d '' file; do echo "$file" # Do something else.done < <(find . -type f -name "*.txt" -print0)Alternatively, if the # do something else is not too complex, you can use find's -exec option and not have to worry about proper delimiting
