How do you check if a file has changed in Linux? The modification time can be set by the touch command. If you want to detect whether the file has changed in any way (including the use of touch , extracting an archive, etc.), check whether its inode change time (ctime) has changed from the last check. That’s what stat -c %Z reports.
How do you run the command every time a file is modified in Linux? Call ls -la when any file changes in this directory/subdirectory. This command shows all the files present in the directory whenever it detects any modification.
How do I monitor a directory in Linux? In Linux, we can use the inotify interface to monitor a directory or a file. We do this by adding a watch to the directory or file. When we add a watch to a file, we can monitor it. For example, we’ll know when a process opens, modifies, reads closes, moves, or deletes the file.
How can you check in realtime for changes made to a file? – Go to: Settings → Preferences → MISC. → and here in the section “File Status Auto-Detection”, make sure to select all three checkboxes ([✓] Enable, [✓] Update silently, [✓] Scroll to the last line after update). and you will see the file being updated in real time, as new log entries are written to it!
