How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. shell-script), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
lang-bash
ls(without-l) is that it's newline delimited, while filenames can be made of any number of lines. With'%s\n', you're printing the file names newline delimited just the same. To print list of file paths in a way that can be processed reliably, you want NUL ('%s\0'or GNUls --zero) instead of NL as the delimiter (and usesort -z,gawk -v RS='\0'etc assuming GNU implementations)
