![]() ![]() The following Linux commands can be used to search files by name. We will also show you how to pipe the output of the find command so that you can easily find the information that you need. In this blog post, we will discuss 6 ways to use the find command to search for files by name. This can be very useful when you need to find a specific file and don’t know where it is located. This command will search through the directories for files that have the specific word in their name. Probably the only solutions that would pass that test would be ones using 'find -print0' piped to xargs or a custom C program.The best way to find files by name in Linux is using the find command with the “-name” option. If you're paranoid, create file and directory names using all 253 legal characters and test. I'm sure Johnny Drop Tables has files with every hex code in the file names. If you're really paranoid, then you'll need to do a find piped to hexdump, split out the results to get all the hex values, and look for one that isn't in the results. That won't work with filenames with newlines in them, but should work with most other filenames. Note the need to unset IFS to restore it to the default. My solution is to pick a character that we assume is not in any filenames, like 0x01 (ctrl-a), and use that: IFS=$'\x01'įILES=( $(find. ![]() Ideally, you would set it to null and use -print0 in find, but null is not allowed as a field separator in Bash. You can set the field separator in Bash to something different. That also kills the newlines from the find command, making them useless as separators. That doesn't work with spaces (or tabs, for that matter). In my case, I wanted to process the file names as elements in an array in Bash, so I wanted something like: FILES=( $(find. Considering that the only illegal characters in filenames are '/' and NULL, there are a lot of edge cases. The find command doesn't have an option to escape special characters, but if it did, it's choice of what to escape might not match the exact needs of your program. There are many different answers, depending on how exactly you want to use the output, as well as what assumptions you are making about what odd characters aren't in the filenames. find has some very useful fine-grained searching capabilities, and is mandatory for tens of thousands of files (at which point you'll run into the shell's maximum number of arguments), but for day-to-day usage it is often unnecessary. *.txt instead, to use every *.txt in the working directory. If you don't want recursiveness, obviously just use. bashrc, so this is always enabled for me (and so are extended globs, which are also useful). I have a line saying shopt -s globstar extglob in my. **/*.txt # feeds all *.txt files to somecommand, recursively In bash, you have to set this: shopt -s globstar If you have a modern shell (bash 4 , zsh, ksh), you can get recursive globbing with globstar ( **). You may find that you are better off using globbing in many cases. The first of the following will feed the filenames to somecommand one at a time, while the second will expand to a list of files: find. Using -print0 is one option, but not all programs support using nullbyte-delimited data streams, so you'll have to use xargs with the -0 option for some things, as Gnouc's answer noted.Īn alternative would be to use find's -exec or -execdir options. ![]()
