Place a + before the number of days to indicate. txt in the directory /home/pat modified in the last two days. This will only return for a search of html if that exists on its own line separately. This command will find all files ending with. This will directly post the output of the. Note this will overwrite any previous contents of. txt file for ex: when we type ls command in terminal it shows list all the files and folder names. -x - match only if the whole lines only. I want to extract name of all files contained in a folder into a.-f - used to indicate a file you want to use which contains a regular expression.searching for html with -v will return everything without html. -h - output the line itself, without the line number or file.-n - returns the line number, but doesn't work with -l. For example, if we search for 'html', then somehtmltext would not match. When we write -rl, this means essentially -r -l, which means search recursively, and return only the file name.īelow is a list of all grep options or switches, which you can add to your query to get the results you need: When we say -r, for example, we mean 'recursive' - i.e. You can string other options together, to get different results. views -e 'html' Options for grep on Linux/Mac The -mindepth and -maxdepth switches ensure we don't get matches from files deeper or shallower in the dev tree.Grep -r. To avoid that problem, the find command is better suited: find dev -mindepth 2 -maxdepth 2 -type f \ Since you say there's hundreds of directories under dev, this approach is not appropriate, although I figure it's worth mentioning here for completeness. Also, when using a list of filenames from a file, you can use redirection instead of invoking a separate cat process, zip files.zip - < zip.lst. Unfortunately there's a limit to command line lengths, and this command may fail if there are too many matching files because the command line would be too long (after expansion). Instead of using ls and grep and zips -, you can use shell globs to select files directly on the zip command line e.g. The grep command searches text files looking for strings that match the search patterns you provide on the command line. Here are several ways to tell grep to ignore different things. For best results you may want to run this command as root. Since 1974, the Linux grep command has been helping people find strings in files. The 2>/dev/null part is there to ignore errors such as when you try reading from files without permissions, like you seem to be doing (based on your answer to Imre L's answer). jpg files from being normalized regardless of their content. Normally the list of matching files can be accomplished simply by running: grep -l MY_Output dev/*/* dev/.?*/* dev/*/.?* dev/.?*/.?* 2>/dev/null sh files have LF in the working directory, and prevent. We can use the mv command to move files with the same extension to a specific directory using wildcard characters. Using these four patterns ensures that you process all the files you want and that you don't get extra matches from other (deeper or shallower) files. One of the most common ways to move files and directories is the mv command-line tool. This is a detail that is missing from secretmike's and Brian Showalter's solutions. More precisely, since the "*" pattern does not match files or directories starting with a ".", you would also want to search for dev/*/*, dev/.?*/*, dev/*/.?* and dev/.?*/.?*. Instead of using ls and grep and zip's -, you can use shell globs to select files directly on the zip command line e.g. As I understand it, in general terms you want to list which folders contain regular files called dev/*/* which themselves contain the string " MY_Output" (case sensitive).
