I'd like to make a script that I can execute every time I sign on to my linux box that keeps track of the time and allows to me to add a remark to a file. So basically once I log in, I run the script, and it outputs the date and time to a text file (log.txt). But that isn't my problem.

first, what does %s represent? I know... (3 Replies)

RUBY-SWITCH(1)RUBY-SWITCH(1)NAME
ruby-switch - switch between different Ruby interpreters
USAGE
ruby-switch --list
ruby-switch --check
ruby-switch --set RUBYVERSION
ruby-switch --auto
DESCRIPTION
ruby-switch can be used to easily switch to different Ruby interpreters as the default system-wide interpreter for your Debian system.
When run with --list, all supported Ruby interpreters are listed.
When --check is passed, ruby-switch will check which Ruby interpreter is currently being used. If the settings are inconsistent -- e.g.
`ruby` is Ruby 1.8 and `gem` is using Ruby 1.9.1, ruby-switch will issue a big warning.
When --set RUBYINTERPRETER is used ruby-switch will switch your system to the corresponding Ruby interpreter. This includes, for example,
the default implementations for the following programs: ruby, gem, irb, erb, testrb, rdoc, ri.
ruby-switch --set auto will make your system use the default Ruby interpreter currently suggested by Debian.
OPTIONS -h, --help
Displays the help and exits.
A NOTE ON RUBY 1.9.x
Ruby uses two parallel versioning schemes: the `Ruby library compatibility version' (1.9.1 at the time of writing this), which is similar
to a library SONAME, and the `Ruby version' (1.9.3 is about to be released at the time of writing).
Ruby packages in Debian are named using the Ruby library compatibility version, which is sometimes confusing for users who do not follow
Ruby development closely.
ruby-switch also uses the Ruby library compatibility version, so specifying `ruby1.9.1' might give you Ruby with version 1.9.2, or with
version 1.9.3, depending on the current Ruby version of the `ruby1.9.1' package.
