How to have a shell script available everywhere I SSH to
- by aib
I have a shell script which I simply cannot do without: bar from Theiling Online
I use SSH a lot and on a variety of *nix servers. However, I am not a system administrator and usually don't have the time or privileges to install it on every server I connect to.
It is apparently a very portable sh script and has command line options to export itself as a shell function, which got me thinking: Could I use one of OpenSSH's subjectively obscure features to export it everywhere I go?
My first thought was to assign the source to an environment variable like BAR = "cat -v" and then execute it on the other side as `$BAR`, but 1) I can't even get the cat example to to work locally, 2) I don't know how to put the script's actual multiline source into an environment variable and 3) I have yet to see a machine with PermitUserEnvironment enabled.
I guess I could even do with an ssh option to write a file called ~/bar at logon, but a more volatile solution would be better.
Calling wget http://.../bar at logon would be unacceptable.
Any ideas?
P.S. Putty-specific solutions, though I doubt any would exist, are also fine.
