A: Rename multiple files which have a variable suffix ```sh find . -type f -print0 \ | grep -z -- '-min.jpg-[[:alnum:]]$' \ | while IFS= read -r -d '' f; do find "$f" -print0 \ | sed -z 's/-min.jpg-[[:alnum:]]$/-min.jpg/' \ | xargs -0 mv "$f"; done; ``` Or, if you prefer a one-liner: ```sh find . -type f -print0 | grep -z -- '...

A: How to run a command on a list of files? In some cases, when you want to apply a pipeline or a complex command to each file, I find it useful to use `while read`: ```sh find . -type d \ | while read d; do find $d -type f -maxdepth 1 \ | head -n3; done; ``` Hardened version: ```sh find . -type d -print0 \ | while IFS= read -...

`generate_lists | xargs some_program` works just as well, and it can pack several arguments into a single program invocation, being faster. In fact, find(1) is just a special case of `generate_lists`, so xargs(1) works in both cases better (the syntax is way simpler). (more) |

Step 2 is conflating two functions:
- Finding all files in every dir.
- Filtering the previous step to just keep the first 3.
The former should be `find $dir -type f -maxdepth 1`.
The latter should be `head -n3`, maybe coupled with a `sort`, depending on what we understand by "first". (more) |

A: How to identify and separate standalone applications from libraries in Linux package lists? This answer is not directly usable under Arch, since I don't know the tools there. I show you a way to do it on Debian, which may inspire you to find a similar way in Arch. With apt-file(1), you can list the files that a package provides. From that list, you can see if the package provides files... (more) |

A: How to list the first x files in each directory Here's my approach: ```sh find l1 -type d \ | while read d; do find $d -maxdepth 1 -type f \ | head -n3; done; ``` If your middle directories also contain files, it will also show them (of course, only the first 3). This is what it shows for me in a tree similar to yours, where I add... (more) |
