how to write a function in bash_profile

Question

how can we write a simple regular function which i can put in my bashprofile which can be used to secure console to any host i want.

but my secure console has to go through a jump host. that is the issue.

function func_name () {
 ssh jumphostname; 
 sc $hostname # from jump host secure console to another host given as input from terminal
}

this function only making to login in to jump host but not to secureconsole in to another host from there.

-bash-4.1$func_name host.me.com should give me console to host.me.com via jumphost

is function for this not possible? do i have to write a script?

Answer 1

Here's how I do it.

1. Create a functions folder at home
2. Write my function as a shell script
3. Reference the file as an alias in my bash_profile
4. Reset the source

Example

mkdir ~/.functions
echo '#!/bin/bash
      echo $1' > ~/.functions/ekho
echo 'alias ekho="sh ~/.functions/ekho"' >> ~/.bash_profile
source ~/.bash_profile

Now you can call your method from any location for ever ever.
