![]() To use this well, you need to learn Linux permissions. In this case, it’s telling grep to only find anything that doesn’t contain the text or string, “Permission denied.” So grep will only show you the results you’re looking for and any errors that don’t match “Permission denied.” Linux FIND by Permissions Example Here’s the basic syntax: find path -name filename Where path is the directory to search, and filename is the name of the file you want to find. v – tells grep to search for anything that doesn’t match text to the left of the -v. To find files with a specific name in Linux, you can use the find command with the -name option. | (called a pipe) – tells Linux to feed the results of whatever is to the left of it to whatever is to its right. It recursively search for the files inside folder myapp/ and returned all the files which are modified in last N minutes. So, to search files modified in last N minutes we need to pass the -N as the numeric argument to -nmin option of the find command, find myapp/ -type f -mmin -N -ls. Now lets look at | grep -v “Permission denied”. find is a fundamental and extremely powerful tool for working with the files on your linux system. Linux: Find files changed in last N minutes. Note that this is not identical to the -executable predicate in GNU find. In this context '+' means 'any of these bits are set' and 111 is the execute bits. For BSD versions of find, you can use -perm with + and an octal mask: find. So 2>&1 means take the standard errors and redirect them, and then put them together with the standard output into one output. On GNU versions of find you can use -executable: find. > – means to redirect whatever output is to the left of it to whatever is to the right of it. You should see that the result contains all the test files and also the test2 directory. ![]() 2 – represents stderr which is short for standard errors output.ġ – represents stdout which is short for standard output Run a find command that will return both file and directory results. Linux find command is a powerful tool that can be used to locate and manage files and directories based on a wide range of search criteria.
