How do I get the find command to print out the file size with the file name Ask Question Asked 15 years ago Modified 6 months ago Viewed 216k times 166 If I issue the find command as follows: find. ] & continue || 1' | sed 's/^ *//'Ī better approach would be to use cut on the ls -l output: ls -l | tr -s ' ' | cut -d ' ' -f 5,9- Attempt to get size of a directory: filesystem error: cannot get file size: Is a directory /dev '/bin/cat' size 50.9KB (52080) '/bin/mouse' : No such file or directory See also. By using read to read ls output leading and trailing spaces will be removed from the word before assigned to a variable, the first word is assigned to the first variable and so on, when all variables are assigned, the remaining words will be added to the last variable, that way we can preserve spaces on the filename. Only way to get size from ls is through verbose listing. (%N will honor QUOTING_STYLE environment variable default is 'shell-escape'). Readers like you help support How-To Geek. Yes, these are different, and we'll explain why. I looked at this question and thought OK this is something you can do fairly easily with find: $ find -maxdepth 1 -type f -printf '%s %f\n' How to Get the Size of a File or Directory in Linux By Dave McKay Published When you use the du command in Linux, it gives you the amount of disk space used by a file or directory, as well as its true size. ![]() find Command Syntax The general syntax for the find command is as follows: find options path. It can also be combined with other tools such as grep or sed. ![]() Note that you must replace the with actual values in the following code examples to run the examples.How to parse output from ls -l verbose listing with a while loop: You can use the find command to search for files and directories based on their permissions, type, date, ownership, size, and more. Search results must meet at least one of the two conditions Furthermore, an OR link can be used or a condition can be negated: Here, a logical AND operation is implicitly assumed. I want to print the size of the file along with the filename/directory. Improve this question I am looking for a Unix command to print the files with its size. Several search parameters can also be combined. Want to improve this question Update the question so it's on-topic for Stack Overflow. But it does give the size of the DVD in bytes and in sectors, and a correct sector size (of 2048 bytes as is usual for DVD). ![]() Below, you’ll find an overview of the most commonly used search parameters: This is followed by a space and the value of the parameter. If you want to use a block size of one megabyte, you can use the -m (megabyte) option, which is the same as -block1M: du -m. A search parameter consists of a hyphen that is immediately followed by the name of the parameter. To use a block size of one byte, use the following command to get the exact sizes of the directories and files: du -block1. First, the command itself is written, followed by a directory path, and a variable number of search parameters.
