Linux - Bash - Grouping Commands

[spbr]

Hi,

Is there a way to group multiple commands, which then can be executed by a single variable?

variable(

             command1

             command2

)

Any Questions?

Thank you

You can create a bash script in order to do this.

 

For example a script with this placed in it. The first line of the script in necessary so that it finds the bash executable.

#/bin/bash

echo "Hello"
echo "World"

There are two separate commands here that can then be run by executing the script. Let's call this script hello. It will output the following

Hello
World

 

Now we need to make the script executable.

chmod 755 hello

 

Now this script can be executed by typing

./hello

However this only works in the current directory.

 

Make a directory for the script, and put it there.

mkdir bin
mv hello ~/bin/hello

 

Now you will want to edit your .bash_profile file to make it so that you can execute the script anywhere by simply typing hello.

 

Open ~/.bash_profile with your editor of choice and include the following command at the bottom of the file.

export PATH=$PATH:/home/user/bin

Some of these steps may require sudo privilege but otherwise, it's the same process.

Or did I misinterpret the complexity of your question?

I guess thats one way

Do you think this would work?

variable='cmd1;cmd2'

variable=$(cmd1 && cmd 2) will work.

no quotations?

From my usage, not when combining commands as it will cause the very next character after the first commands to be an argument for the first command. I don't do a lot bash scripting but that's what I've gathered while testing it.

 

@SCHISCHKA will likely know more than me.

yes you can do functions in bash

Quote

function functionName {

echo hello

ls /

echo "OPTIONAL: this put the first argument $1 that you pass into the function into the ls command"

ls $1

echo " this will put the second variable $2 into the find command"

find $2

}

then to execute

Quote

functionName argument1 argument2
