     Use inotify-tools.

     The linked Github page has a number of examples; here is one of them.

     #!/bin/sh-cwd=$(pwd)-inotifywait -mr \ --timefmt '%d/%m/%y %H:%M' --format '%T %w %f' \ -e close_write /tmp/test |while read -r date time dir file; do changed_abs=${dir}${file} changed_rel=${changed_abs#"$cwd"/} rsync --progress --relative -vrae 'ssh -p 22' "$changed_rel" \ [email protected]:/backup/root/dir && \ echo "At ${time} on ${date}, file $changed_abs was backed up via rsync" >&2done

     You may try entr

     tool to run arbitrary commands when files change. Example for files:

     $ ls -d * | entr sh -c 'make && make test'-

     or:

     $ ls *.css *.html | entr reload-browser Firefox-

     or print Changed! when file file.txt is saved:

     $ echo file.txt | entr echo Changed!-

     For directories use -d, but you've to use it in the loop, e.g.:

     while true; do find path/ | entr -d echo Changed; done-

     or:

     while true; do ls path/* | entr -pd echo Changed; done-

     I use this script to run a build script on changes in a directory tree:

     #!/bin/bash -euDIRECTORY_TO_OBSERVE="js" # might want to change thisfunction block_for_change { inotifywait --recursive \ --event modify,move,create,delete \ $DIRECTORY_TO_OBSERVE}BUILD_SCRIPT=build.sh # might want to change this toofunction build { bash $BUILD_SCRIPT}buildwhile block_for_change; do builddone

     Uses inotify-tools. Check inotifywait man page for how to customize what triggers the build.

   • How to run a shell script on a Unix console or Mac terminal?

     Top Answer

     To run a non-executable sh script, use:

     sh myscript-

     To run a non-executable bash script, use:

     bash myscript

     To start an executable (which is any file with executable permission); you just specify it by its path:

     /foo/bar/bin/bar./bar

     To make a script executable, give it the necessary permission:

     chmod +x bar./bar

     When a file is executable, the kernel is responsible for figuring out how to execte it. For non-binaries, this is done by looking at the first line of the file. It should contain a hashbang:

     #! /usr/bin/env bash

     The hashbang tells the kernel what program to run (in this case the command /usr/bin/env is ran with the argument bash). Then, the script is passed to the program (as second argument) along with all the arguments you gave the script as subsequent arguments.

     That means every script that is executable should have a hashbang. If it doesn't, you're not telling the kernel what it is, and therefore the kernel doesn't know what program to use to interprete it. It could be bash, perl, python, sh, or something else. (In reality, the kernel will often use the user's default shell to interprete the file, which is very dangerous because it might not be the right interpreter at all or it might be able to parse some of it but with subtle behavioural differences such as is the case between sh and bash).

     Most commonly, you'll see hash bangs like so:

     #!/bin/bash

     The result is that the kernel will run the program /bin/bash to interpret the script. Unfortunately, bash is not always shipped by default, and it is not always available in /bin. While on Linux machines it usually is, there are a range of other POSIX machines where bash ships in various locations, such as /usr/xpg/bin/bash or /usr/local/bin/bash.

     To write a portable bash script, we can therefore not rely on hard-coding the location of the bash program. POSIX already has a mechanism for dealing with that: PATH. The idea is that you install your programs in one of the directories that are in PATH and the system should be able to find your program when you want to run it by name.

     Sadly, you cannot just do this:

     #!bash

     The kernel won't (some might) do a PATH search for you. There is a program that can do a PATH search for you, though, it's called env. Luckily, nearly all systems have an env program installed in /usr/bin. So we start env using a hardcoded path, which then does a PATH search for bash and runs it so that it can interpret your script:

     #!/usr/bin/env bash

     This approach has one downside: According to POSIX, the hashbang can have one argument. In this case, we use bash as the argument to the env program. That means we have no space left to pass arguments to bash. So there's no way to convert something like #!/bin/bash -exu to this scheme. You'll have to put set -exu after the hashbang instead.

     This approach also has another advantage: Some systems may ship with a /bin/bash, but the user may not like it, may find it's buggy or outdated, and may have installed his own bash somewhere else. This is often the case on OS X (Macs) where Apple ships an outdated /bin/bash and users install an up-to-date /usr/local/bin/bash using something like Homebrew. When you use the env approach which does a PATH search, you take the user's preference into account and use his preferred bash over the one his system shipped with.

   • How to run a shell script on a Alpine Docker container on startup?

     Top Answer

     Answered Sep 04, 2019 · 2 votes

     You should create a shell file to be copied inside a new container and then setup the container entrypoint as the shell script you created, synthax would be like

     FROM <docker/alpine-image>#.... somecodeUSER rootCOPY /localmachinelocation/entrypoint.sh /containerlocation/entrypoint.shRUN chmod 544 /var/www/webapp/entrypoint.sh#.... somecodeCMD /containerlocation/entrypoint.sh

     You could specify the user you need to run the script. Chmod ensure the script would be runnable by the owner of the script, you could change it for security matters.

     Let's say you have your script in /home/user/script.sh, you could do

     FROM <docker/alpine-image>USER rootCOPY /home/user/script.sh /root/entrypoint.shRUN chmod 544 /var/www/webapp/entrypoint.shCMD /root/entrypoint.sh
