rm -r command not working inside of shell in macos catalina - bash

I am new to shell scripting. I wrote basic simple.sh file on mac. I put my .sh file to /usr/local/bin directory and I added sh file to the chrometab so as to run every minute. My sh file works fine on standalone terminal screen but I can't delete the folder I want on crometab. Could you please help me? What's my problem? I tried to crontab -e, sudo crontab -e but I can't delete folder I want.
os: macOs Catalina 10.15.7
#! /bin/bash
downloadsDirectoryPath="/Users/Odin/Downloads/"
sampleFolderPath=$downloadsDirectoryPath"sampleFolder"
logFilePath=$downloadsDirectoryPath"log.txt"
sudo rm -rf $sampleFolderPath # this row not works, why???
echo "this row absolutely works" >> $logFilePath

Check if you have the permissions to remove the folder.
Likely you can try adding sudo before your command like this
sudo rm -rf $sampleFolderPath
Else you can just set the folder permissions using chmod 755 -R foldername

I solved the problem with allow full disk access permission to the cron and crontab. Thanks for help #GordonDavisson

Commands without sudo in bash do not work

I am running a bash script and these commands in the script will not work without sudo in front of them. The script.sh is located in a folder such as /jobs/script.sh
Example of commands I am trying to run in the script.sh -
mv /var/app/myapp /var/app/myapp.old
rm file.tar.gz
tar -xzf /home/ubuntu/file.tar.gz -C /var/app/
All the above work if I add sudo in front of them.
I am trying to figure out what permissions are required for them to work without adding sudo in the script.
I have tried giving the script.sh rwx permissions and changing owner to root.
I'm learning permissions in linux, so I'm new to this. Basically what permission should the script.sh have so that I dont have to use sudo in the bash file? Any insight would greatly help.
When you run sudo <some command>, then <some command> is run by the root user (Super user do). The reason you might need to run any command using sudo is because the permissions on the files that command reads/writes/executes are such that only the "Super user" (root) has that permission.
When executing the command mv fileA fileB, the executing user would need:
Write permission to fileB if fileB already existed
Write permission to the directory containing fileB
From what you said it’s most likely you want read and write permissions you can achieve this with chmod
Chmod +[permission] filename
(+ is used to add permission you can also use - instead to remove it)
Where permissions can be:
r —> read
w—> write
x —>excecute
... and more
FOR EXAMPLE: it seems you write permissions for the first file so :
chmod +w /var/app/myapp
Will fix problem

Bash-running a script in background

I have a script(func_test) that works well when i invoke it from my terminal. I need to run the script automatically on boot-up and so i have copied it in /etc/init.d and changed its execution mode and linked it to S99func_test under /etc/rc2.d. But upon reboot I'm getting syntax error in that script. Any idea why I'm getting the error although it works fine with my terminal?
Here is the code used to invoke the script for the 1st time:
#!/bin/bash
cd /opt/bin/
cp func_test /etc/init.d/
cp test_file /etc/init.d
chmod 755 /etc/init.d/func_test
chown root:sys /etc/init.d/func_test
ln /etc/init.d/func_test /etc/rc2.d/S99func_test
ln /etc/init.d/test_file /etc/rc2.d/S99test_file
(the script is dependent on another file(test_file) and i have copied the same to init.d)
Probably you forgot slash at the end of line
cp test_file /etc/init.d/
and I recommend to use ./ to copy files from current directory:
cp ./func_test /etc/init.d/

How to run a script file on Mac?

I have searched on how to run a script file on Mac but nothing works for me.
Every time I tried sudo script-name the terminal responds with
-bash: /Users/macuser/Desktop/tesseract-3.01: is a directory
The file I want to run is called start and it's located in tesseract-3.01 directory on the desktop.
simply do
/Users/macuser/Desktop/tesseract-3.01/start
or if it's actually called start.sh
/Users/macuser/Desktop/tesseract-3.01/start.sh
you might also want to do
chmod +x /Users/macuser/Desktop/tesseract-3.01/start.sh
to change the script to be executable before you run the script
sudo /Users/macuser/Desktop/tesseract-3.01/start
You have to indicate the script name, but it looks like you were only specifying the directory.
You could also cd to the directory and then run it like so:
cd /Users/macuser/Desktop/tesseract-3.01
sudo ./start
Try
sudo ./Users/macuser/Desktop/tesseract-3.01/start.sh
or
cd /Users/macuser/Desktop/tesseract-3.01
then
sudo ./start.sh

modify file content

I'm installing a lighttpd server on a remote machine using a bash script. After installation, I need to configure the port for the server. The system says I don't have permission to modify the file /etc/lighttpd/lighttpd.conf even though I do
sudo echo "server.bind=2000" >> /etc/lighttpd/lighttpd.conf
How shall I modify this?
What you're doing is running echo as root, then trying to append its output to the config file as the normal user.
What you want is sudo sh -c 'echo "server.bind=2000" >> /etc/lighttpd/lighttpd.conf'
Try to change the file permission using chmod
$ sudo chmod a+x /etc/lighttpd/lighttpd.conf
If you don't have the right to change the file /etc/lighttpd/lighttpd.conf check the man page of lighthttpd. If you can start it with a different config file, then create a config file somewhere and start lighthttpd with it.
The problem is that the bit on the right of >> is not run under sudo. Either use sudo -i to bring up a root shell a superuser and run the command, or just use an editor as mentioned before.

Tomcat startup script permission on Mac OS X

I'm struggling with a Mac OS X 10.5.8 that I've started using recently for development. I successfully installed tomcat and create launchd.conf for my environment variables.
I believe it works fine. Coz I can build a project with Netbeans using maven and cargo plugins successfully so i found online a script for start and stop the tomcat
#!/bin/bash
case $1 in
start)
sh /Library/apache-tomcat-6.0.20/bin/startup.sh
;;
stop)
sh /Library/apache-tomcat-6.0.20/bin/shutdown.sh
;;
restart)
sh /Library/apache-tomcat-6.0.20/bin/shutdown.sh
sh /Library/apache-tomcat-6.0.20/bin/startup.sh
;;
*)
echo "Usage :start|stop|restart"
;;
esac
exit 0
That script was created in nano in sudo sh
but when i want to run it. is spit out this
sh: /usr/bin/tomcat: Permission denied
I've added chmod 755 *.sh and *.bat inside /Library/apache-tomcat-6.0.20/bin
Still access denied so what do I go around that? I have the admin privileges on the machine.
Thanks for reading
Go to Tomcat bin directory and run the below command:
chmod +x *.sh
This worked for me.
Where did you install the tomcat script to? I'd recommend you install it to /usr/bin. Once installed, make sure the permissions are correct (i.e. chmod 755 /usr/bin/tomcat). You can then confirm with ls -l /usr/bin/tomcat.
If you still get errors once the permissions on /usr/bin/tomcat are correct, then you can add the following two lines following the #!/bin/bash line.
set -x
set -v
With the above lines, bash will output additional information that will allow you to tell what's being executed and where the error is happening.
1) Go to the tomcat directory, which preferably should be "/usr/local/folder-name"
2) Check for the permissions for the folder: ls -l
3) Change the permissions using: sudo chmod -R 755 folder-name
4) Change the owner to the current owner: sudo chown -R owner-name:group-name folder-name
e.g sudo chown -R userName:admin folder-name
Try executing the script again and it should work.
