this has probably been done before and it's not that clever. but i find it useful - it saves me adding aliases to .bashrc for machines i commonly ssh to:
This goes in a directory which is added to my path, and then gets symlinked to. the name of the symlink being the target machine, or an abbreviation of it.

# ls ssh-targets: box1 -> box2 ->
so now typing box1 will ssh me to that machine (i then also obv get tab completion on machine names)
#!/usr/bin/perl my $file=$0; # what machine are we looking at? $file=~s#^(?:.*/)?([^/]+)$#$1#; my $dest; # a config hash for expanding the name, and choosing the user. my $places={ box=>{full=>"boxwithlongname"}, home=>{full=>"blahblah",user=>"alexk"} }; # if i have many machines with the same long name - abbreviate to box # (as in hash above), so box1 goes to boxwithlongname1 etc my ($short,$number)=$file=~/^(\D+)(\d?)$/; my $hash=$places->{$short}; $dest=$hash->{full}?$hash->{full}.$number:$file; $user=$hash->{user}||"alex"; # and ssh to it. exec("ssh $user\@$dest @ARGV") if $dest;

to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
