I have a file called butcher and at the top of this file I put #!/bin/bash. The I changed permissions like so chmod 777 butcher. however when I try to run the script by typing butcher, I get this error: -bash: butcher: command not found. I'm not sure how to fix it, please help! Thank you in advance! :D
The file would have to be on your $PATH for your system to find it and execute it. Otherwise, the entire path to the file would have to be specified.
To show your path try:
echo $PATH
To run your script, either put it in one of those locations (such as /usr/local/bin), or go to the directory butcher is located in and run ./butcher.

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.
Kind Regards

Right now, I have shellScript.sh and test_me.py in a folder ABC/def. shellScript.sh calls test_me.py. I'm trying to call shellScript.sh from the ABC folder. So far, I keep on getting "No such file or directory" errors.
I've tried calling the python script from the shell script such as:
python /ABC/def/test_me.py
but this still gives me the same error.
How do I fix this?
Make sure your home directory starts by a capitalize H, if it does not (which is highly probable) your script won't work.
If the problem is not in the path or filename, then it could be in the way you are executing the shellScript.sh:
./shellScript.sh
might fix it provided you have the proper execute bit set on the script file. If not, try this:
sh /proper/path/to/shellScript.sh
If that does not fix it, then try to cd to the directory in the script before the python line:
cd /to/proper/folder
python test_me.py
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
First off I am very very new to shell scripting. I am trying to write a script that takes in one parameter and then copies a folder in a different directory naming it using the parameter. This is the current code that I have:
#!/bin/sh
cd /var/www/html/fbplugin/chrome
sudo mkdir temp/$1
sudo cp -rf "/var/www/html/fbplugin/chrome/fbplugin" "/var/www/html/fbplugin/chrome/temp/$1"
When I run this code it says can't cd to /var/www/html/fbplugin/chrome. I'm not sure why it is saying this because I know the directory exists. I have copied the line directly and it works in terminal. If anyone could help me out that would be great.
If it matters in order to run the script I am typing "sh build.sh"
If that directory really exists, then you must have executed that script with a different user (cron, webserver, etc).
Check the rights for that directory.
I don't know why you're getting the error about cd, but it looks like you could just use absolute paths throughout. That would solve the larger problem of the script working correctly.
I am on Mac's OS 10.6, and I am trying to learn a thing or two about shell scripting. I understand how to save a shell script and make it executable, but I am wondering what I can do or where I can save the file to make it global (that is, accessible no matter what folder I am in).
For example, if I save a .sh file in the /Users/username/ directory and make it executable, I can only execute that script in that specific directory. If I navigate to /Users/username/Downloads, for example, I can't execute the script.
Also, any suggestions of resources for learning more about shell scripting would be helpful. Thanks
/usr/local/bin would be the most appropriate location. Mac OS X has it in the PATH by default
There are two ways to do it -
Put your script in usr/local/bin and make sure it is executable(chmod +x my_script)(This is already set in the path, you can check by doing an echo $PATH)
Create a folder in your home directory called bin. (For your personal scripts)
cd ~ (Takes you to your home directory)
mkdir bin (create a bin folder)
vim .bash_profile (to set path environment variable)
export PATH=~/bin:$PATH (Press i then add this line and then do esc and type :wq)
Now you can just type the name of your script and run it from anywhere you want.
** NOTE: If you want to run the script with a shortened command rather than typing your entire filename, add the following to your .bash_profile:
alias myscript='my_script.sh'
Then you can run the script by simply typing myscript. (you can sub in whatever alias you'd like)
Traditionally, such scripts either go in ~/bin (ie: the bin directory in your home directory) or /usr/local/bin/ The former means the script will only work for you, the latter is for scripts you want anybody on the system to be able to run.
If you put it in ~/bin, you may need to add that to your PATH environment variable. /usr/local/bin should already be on the path.
In mac operating system
Open bash ~/.bashrc file.
add path of your script in your bashrc file , using
export PATH="$PATH:/Users/sher.mohammad/Office/practice/practiceShell"
Open your ~./bash_profile file and add [[ -s ~/.bashrc ]] && source ~/.bashrc
open new terminal window
Now whenever you will open your terminal your script will be loaded
This one is super easy if you are familiar with your bashrc file! This will entirely use just your .bashrc file and takes 2 seconds to accomplish.
(I use Arch Linux Manjaro so I use .bashrc located in my home directory)
The code to be placed in your .bashrc file:
# Simple bashrc method to launch anything in terminal from any directory
YOURCOMMAND () {
cd /path/to/directory/containing/your/script/ && ./YOURSCRIPT
}
As you can see, first you use the simple 'cd' command and give it the directory of the scripts location, then use '&&' so that you can make the next command executed right after, and finally open your script just as you would normally! Super easy and saved right in your .bash file! :)
Hope I've helped someone!
Sincerely,

On using bash shell, write that script as function and then put it to the .bashrc or source the file which containing that function by "source file_name"
Now execute the script by function call in the shell.
Either saving it in /usr/bin (or any other directory present in PATH) or editing PATH to include the directory you saved it in will basically make it run in any directory.
from the working directory of 'script.sh'" mv [script.sh] /usr/local/bin"( not tested but seems to be the least complex way IMO.)
You should put it in the global executable directory on your machine. I think that would usually be /usr/bin on Unix-based operating systems (this would however most often require super user privileges on that machine).
You could also put it in any other directory that is in the $PATH environment variable, although it would only work for those users who have that directory in that variable.
You can find the value of $PATH by typing echo $PATH in a shell. The directories are separated by :.
