-ls lists the resulting files (the files that have been modified in the last N days) in ls -dils format on standard output.-mtime -N is used to match files that had their data modified in the last N days.
Replace it with the path of the directory where you want to look for files that have been modified in the last N days /directory/path/ is the directory path where to look for files that have been modified.find is the Unix command line tool for finding files (and more).To find the files that have been changed (with the files data modification time older than) in the last N days from a directory and subdirectories, use:
BASH FIND FILE PATH HOW TO
The idea is to familiarize you with a few techniques that could make your work less error-prone and more fun.This article explains how to find all files in a directory that have been changed in the last N minutes or days, or those with a modification date older than N minutes or days, with examples. Let’s first cover the most basic way to use the Bash find command. A symbolic link is a Linux shortcut file that points to another file or a folder on your computer. The find command finds or searches also for symbolic links (symlink). I am sharing what I know and what I deal with daily. The find command allows you to define those criteria to narrow down the exact file (s) you’d like to find. There is certainly more to Bash than I was able to cover in this two-part blog post. There are many other complex actions I can perform on the remote host. One way is to enter: $> ssh remote_host 'bash -s' exec ssh remote_host ARG1=FOO ARG2=BAR 'bash -s' printf %s I can also execute a local script on the remote host without having to copy the script over to the remote server. This command runs ls /etc on the remote host. To see if a remote server is running a web, database, SSH, or any other service, run: $> timeout 3 bash -c ‘ timeout 3 bash -c ‘ ssh remotehost ls /etc These tools are handy, but they aren't installed by default on all systems.įortunately, there is a simple way to test a connection without using external tools. I use Telnet, netcat, Nmap, and other tools to test whether a remote service is up and whether I can connect to it. To delete files older than 30 days, run: $> find /tmp -type f -mtime +30 -exec rm -rf 2> to_stderrĪs you can see, only "Hello world" is printed on the screen, but the output of the failed commands is written to the to_stderr file. To list files older than 30 days, I simply run: $> find /tmp -type f -mtime +30 Let's get more familiar with this command. With find I can list files older or newer than a specific date, delete them based on that date, change permissions of files or directories, and so on. It is extremely useful in interactive shells. The find command is probably one of the most used tools within the Linux operating system. For example, the $PATH shell variable can be expanded by running: $> echo $PATH Use the echo command to expand variables. These are a few frequently-used variables: $PATH Why would I use hostname when I can use $HOSTNAME, or why would I use whoami when I can use $USER? Bash variables are very fast and do not require external applications. The Bash variables are set by the shell when invoked. In this segment, I cover shell variables, find, file descriptors, and remote operations. In part one, I covered history, last argument, working with files and directories, reading files, and Bash functions. This blog post is the second of two covering some practical tips and tricks to get the most out of the Bash shell. How well do you know Linux?
