If you have Cabal-Install installed, the following two commands should install the latest SCC package on your system:
cabal update cabal install scc
If everything goes well, there should be executable named shsh. On Unix it gets installed in your $HOME/.cabal/bin/ directory by default.
To see the options supported by shsh, type shsh --help and you'll get:
Usage: shsh (-c <command> | -f <file> | -i | -s) -c --command Execute a single command -h --help Show help -f file --file=file Execute commands from a script file -i --interactive Execute commands interactively -s --stdin Execute commands from the standard input
Here are a few simple command examples:
|Bash + GNU tools||shsh|
|echo "Hello, World!"||echo "Hello, World!\n"|
|wc -c||count | show | concatenate|
|wc -l||foreach line then substitute x else suppress end | count | show | concatenate|
|grep "foo"||foreach line having substring "foo" then append "\n" else suppress end|
|sed "s:foo:bar:"||foreach substring "foo" then substitute "bar" end|
|sed "s:foo:[\\&]:"||foreach substring "foo" then prepend "[" | append "]" end|
|sed "s:foo:[\\&, \\&]:"||foreach substring "foo" then id; echo ", "; id end|
Using the framework from Haskell
The shell interface is basically only syntax on top of the underlying EDSL (embedded domain-specific language) in Haskell. If you require anything more than stringing together of existing components using existing combinators, you'll need to write Haskell code.
