I'm currently running Prettier in a particular directory when I save the file with entr:
ls *.{tsx,ts} | entr prettier -w "*"
However, it would be great to only run for the file that has just been changed/saved, instead of the entire directory, I am pretty new to the command line and would love to learn how to achieve this!

I want to modify *.ica files (to launch Citrix apps) when they are downloaded (to add a transparent Key Passthrough option for remote desktop), so I settled on using entr to monitor the directory, and call then another script (which invokes sed) to update all ica files.
while true; do
ls *.ica | entr -d ~/Downloads/./transparentKeyPassthrough-CitrixIca.sh
done
However, this only works when there is already an .ica file in the directory. If the directory has no *.ica files when first executed, entr errors with:
entr: No regular files to match
Putting a dummy ica file suffices, in which case the new (real) ica file will be detected by entr, and then acted on.
Is there a better way to do this?
The alternative I can think of is to use entr to watch the whole directory for any changes, and if so, run ls -l *.ica and if the change resulted in a new ica file, and then in turn, run the above script.
It seems inelegant and complicated to nest entr that way, so wanted to know if there is some simple option I am missing.
I'm trying to slim down the process it takes to rebuild my php/react app, but I'm having trouble with yarn/npm commands. Is there a way to write a script that reads Powershell syntax? Right now I'm just copy pasting it since yarn isn't reading it properly.
Example:
yarn copy to run cp -r src/services build/services; cp -r vendor build/vendor
I'm trying to follow a walkthrough and this is one of the steps, "go to that same folder in Terminal (if you can't do that you should probably quit now)" I'm not very familiar with Mac's Terminal, but don't feel like quitting. If it helps, I need to run a grep -r "what I'm looking for" command on the file. I really have no idea what I need to do to run that command, but the rest of the walkthrough is pretty thorough, so I know I can follow the next few steps.
You need to move to the directory where that file is stored, for this the command is cd. For example lets say the file is located in a directory names MyDir in the Desktop, the command will be
cd /Users/{YOUR_USERNAME_HERE}/Desktop/MyDir
You can run ls command here to check if the file is actually present in this directory or not
I have currently put together a script to move files from one directory to another.
This has gone ok however I was wondering if there was a way via a shell script to get it to run from anywhere on the server e.g I give the script for someone to use on their server and they can put the script anywhere and it will run.
I know a workaround is to put the script in /usr/local/bin or usr/bin and you can run it from anywhere but that is not what I want.
Is there a way that my script will auto run from usr/local/bin regardless of if it is in /scripts for instance?
Please see my script below:
#!/bin/sh -x
mkdir -p /var/Alitest
echo "This is a test that I have created. This is to
see if the output is successful I normally do this manually but a script is required" > /var/Alitest/action.txt
sed -i 's/This is a test that I have created/The test has been successful/g' /var/Alitest/action.txt
chmod 744 /var/Alitest/action.txt
chown root:root Alitest/action.txt
mv /var/Alitest/action.txt /script/action.txt
Any help would be greatly appreciated :)
Also in my log output for the script the following error is shown:
sed: 1: "/var/Alitest/action.txt": invalid command code A
Any ideas?
You can make a soft link in /usr/local/bin for your script. Then it will be in everyone's path to be executed.
e.g. ln -s /script/yourscript.sh /usr/local/bin/yourscript.sh
After reviewing the matter further I have decided the the best way to action this is to add the folder destination e.g /scripts to my path.
This can be done by vimming into the .bashrc file on the server and adding the below line:
export PATH=/dir_name:$PATH
remember to refresh the profile in order for the changes to take effect.
You can check if this has been successful by running the below command:
echo $PATH
There is no way to get your script to do this however this would be better then a softlink as if you add it to $PATH then you do not have to go through the task of adding softlinks each time.
Thank you all for your help.

I am very new to bash and using .sh files. I am trying to run the program aescrypt by calling it in a .sh file as follows (aescrypt is in the same directory as the .sh file) :
./aescrypt -e -p password file.txt
It throws the following error:
./aescrypt no such file or directory
Am I doing it wrong?
ps- I realy don't want to add it to the PATH variable as I will be using this on more than one computer that resets every day.
The location of the script is irrelevant. The thing that matters is the working directory of the process executing the script. The simplest solution really is to add aescrypt to a standard location like /bin or /usr/bin. If neither of those is acceptable, perhaps /usr/local/bin is an option. Otherwise, just use the full path of aescrypt in your script. Either hard code it, or if it is in the same directory as the script, try:
$(dirname $0)/aescrypt ...
(Note that hardcoding is more reliable, but less flexible. If you move the executable, the script will break. But using dirname will break if the script changes directory during execution.)
how about if you call the program like ./aescrypt.sh, thats the way to call an .sh programm througt the terminal
First off all, you have also to change the permissions of the file to make it executable, the way to make that is to write in the terminal, the command:
sudo chmod 765 aescrypt.sh
For that you have to be located where the file is
