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.

So I'm trying to write a script that will let me run a command to initialize some things. To be more specific, let's say I start in my home directory but to run this command I want I must be in a directory three folders deep into the home directory.
My script looks generically like this.
#!/bin/sh
cd home/path/to/final/directory/
command
Now usually, when I cd to this directory I can run the command on the command line and everything works fine.
When I tried to use a script to do it, the command line throws an error saying that that command isn't recognized like the computer doesn't know where to look.
The temporary fix I used was making a symbolic link to the directory I wanted but I was hoping someone could help me so that when I ssh to this node this script can be run immediately so I will not have to go into the deep directory, run the command and leave again.
Try defining full paths, for example:
#!/bin/sh
cd $HOME/path/to/final/directory && /path/to/your/command
In this case, it will try to cd into your defined directory but if it can't find the dir it will not run the command, this because of the &&
To test before running the command you could do a ls, for example:
cd $HOME/path/to/final/directory && ls
I have currently put together a script to move files from one directory to another.
This has gone ok however I was wondering if there was a way via a shell script to get it to run from anywhere on the server e.g I give the script for someone to use on their server and they can put the script anywhere and it will run.
I know a workaround is to put the script in /usr/local/bin or usr/bin and you can run it from anywhere but that is not what I want.
Is there a way that my script will auto run from usr/local/bin regardless of if it is in /scripts for instance?
Please see my script below:
#!/bin/sh -x
mkdir -p /var/Alitest
echo "This is a test that I have created. This is to
see if the output is successful I normally do this manually but a script is required" > /var/Alitest/action.txt
sed -i 's/This is a test that I have created/The test has been successful/g' /var/Alitest/action.txt
chmod 744 /var/Alitest/action.txt
chown root:root Alitest/action.txt
mv /var/Alitest/action.txt /script/action.txt
Any help would be greatly appreciated :)
Also in my log output for the script the following error is shown:
sed: 1: "/var/Alitest/action.txt": invalid command code A
Any ideas?
You can make a soft link in /usr/local/bin for your script. Then it will be in everyone's path to be executed.
e.g. ln -s /script/yourscript.sh /usr/local/bin/yourscript.sh
After reviewing the matter further I have decided the the best way to action this is to add the folder destination e.g /scripts to my path.
This can be done by vimming into the .bashrc file on the server and adding the below line:
export PATH=/dir_name:$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

I have a shell script which calls for different executables from it.
The shell script and the executables are within same directory and I am trying to run it from there. Still, on running, I get the error, "executable" not found- No file/directory exists.
What should I do???
First, You need to provide permission to the File :
chmod +x filename
Then, execute the binary file by,
./filename
The current directory is typically not in your command path, for security reasons. You need to provide the path explicitly, that is
./mycommand
instead of
mycommand
(Keep in mind, though, that this will break if you run the script from a different directly. ./mycommand is relative to the directory you run from, not the directory where the script is stored.)
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
