How do I run a shell script without using sh or bash commands

Question

I have a shell script which I want to run without using the  sh  or  bash  commands  For example   Instead of  sh script sh  I want to use  script sh  How can I do this   P S   i  I don t use shell script much and I tried reading about aliases  but I did not understand how to use them     ii  I also read about linking the script with another file in the PATH variables  I am using my  university server and I don t have permissions to create a file in those locations

In this example the file will be called myShell

First of all we will need to make this file we can just start off by typing the following:

sudo nano myShell

Notice we didn't put the .sh extension? That's because when we run it from the terminal we will only need to type myShell in order to run our command!

Now, in nano the top line MUST be #!/bin/bash then you may leave a new line before continuing.

For demonstration I will add a basic Hello World! response

So, I type the following:

echo Hello World!

After that my example should look like this:

#!/bin/bash
echo Hello World!

Now save the file and then run this command:

chmod +x myShell

Now we have made the file executable we can move it to /usr/bin/ by using the following command:

sudo cp myShell /usr/bin/

Congrats! Our command is now done! In the terminal we can type myShell and it should say Hello World!

Add a  shebang  at the top of your file      bin bash   And make your file executable  chmod  x script sh    Finally  modify your path to add the directory where your script is located   export PATH  PATH  appropriate directory    typically  you want  HOME bin for storing your own scripts

Make any file as executable    Let s say you have an executable file called migrate linux amd64 and you want to run this file as a command like  migrate    First test the executable file from the file location     oracle localhost     migrate linux-amd64  Usage  migrate OPTIONS COMMAND  arg            migrate   -version   -help    Options    -source          Location of the migrations  driver   url    -path            Shorthand for -source file   path    -database        Run migrations against this database  driver   url    -prefetch N      Number of migrations to load in advance before executing  default 10    -lock-timeout N  Allow N seconds to acquire database lock  default 15    -verbose         Print verbose logging   -version         Print version   -help            Print usage  Commands    goto V       Migrate to version V   up  N        Apply all or N up migrations   down  N      Apply all or N down migrations   drop         Drop everyting inside database   force V      Set version V but don t run migration  ignores dirty state    version      Print current migration version    Make sure you have execute privileges on the file     -rwxr-xr-x  1 oracle oinstall   7473971 May 18  2017 migrate linux-amd64     if not  run chmod  x migrate linux-amd64 Then copy your file to  usr local bin  This directory is owned by root  use sudo or switch to root and perform the following operation   sudo cp migrate linux-amd64  usr local bin sudo chown oracle oracle  user local bin migrate linux amd64    Then create a symbolic link like below    sudo ln  usr local bin migrate linux amd64  usr local bin migrate sudo chown oracle oracle  usr local bin migrate    Finally add  usr local bin to your path or user profile   export PATH    PATH  usr local bin    Then run the command as  migrate     oracle localhost   migrate Usage  migrate OPTIONS COMMAND  arg            migrate   -version   -help    Options    -source          Location of the migrations  driver   url    -path            Shorthand for -source file   path    -database        Run migrations against this database  driver   url    -prefetch N      Number of migrations to load in advance before executing  default 10    -lock-timeout N  Allow N seconds to acquire database lock  default 15    -verbose         Print verbose logging   -version         Print version   -help            Print usage  Commands    goto V       Migrate to version V   up  N        Apply all or N up migrations   down  N      Apply all or N down migrations   drop         Drop everyting inside database   force V      Set version V but don t run migration  ignores dirty state    version      Print current migration version

Just make sure it is executable  using chmod  x   By default  the current directory is not on your PATH  so you will need to execute it as   script sh - or otherwise reference it by a qualified path   Alternatively  if you truly need just script sh  you would need to add it to your PATH    You may not have access to modify the system path  but you can almost certainly modify the PATH of your own current environment    This also assumes that your script starts with something like    bin sh   You could also still use an alias  which is not really related to shell scripting but just the shell  and is simple as   alias script sh  sh script sh    Which would allow you to use just simply script sh  literally - this won t work for any other   sh file  instead of sh script sh

Enter     bin sh  before script  Then save it as script sh for example  copy it to      HOME bin     or      HOME usr bin The directory can be different on different linux distros but they end with      bin      and are in home directory     cd  HOME bin     or      HOME usr bin Type     chmod 700 script sh And you can run it just by typing     run sh     on terminal  If it not work  try     chmod  x run sh  instead of  chmod 700 run sh

These are the prerequisites of directly using the script name   Add the shebang line     bin bash  at the very top  Use chmod u x scriptname to make the script executable  where scriptname is the name of your script   Place the script under  usr local bin folder   Note  I suggest placing it under  usr local bin because most likely that path will be already added to your PATH variable    Run the script using just its name  scriptname   If you don t have access to  usr local bin then do the following   Create a folder in your home directory and call it bin   Do ls -lA on your home directory  to identify the start-up script your shell is using  It should be either  profile or  bashrc   Once you have identified the start up script  add the following line  PATH  quot  PATH  HOME bin quot    Once added  source your start-up script or log out and log back in  To source  put   followed by a space and then your start-up script name  e g     profile or    bashrc  Run the script using just its name  scriptname

You have to enable the executable bit for the program   chmod  x script sh   Then you can use   script sh  You can add the folder to the PATH in your  bashrc file  located in your home directory   Add this line to the end of the file   export PATH  PATH  your folder here
