Shell support

[matz3ibm]

Hi Scott,

probably not found the right workaround or command yet, but the Operations team and I were looking on how to switch to shell mode from jsqsh, eg. for doing some researching in hdfs, run some scripts or ETL jobs. In the \help I found:
"2> go | grep test | more"
.... but would like to have something like

\sh to invoke a "configurable shell"
to execute bash, ksh, sh, probably with cmd line as parameter- similar to vi ":sh" command.

Using this with the jsqsh alias command with an additional template mechanism would be very practible:
\alias listdnodes @@cluster@@='\sh ./opt/IBM/tools/listnodes.pl -s=dnodes -c @@cluster@@'

(I think there is a little error on the alias wiki page, "pre-argumented commands": https://github.com/scgray/jsqsh/wiki/alias in example: 1> \alias '\prod'='\connect -U sa -S prod-db -d mssql-jtds' ==> then it's called with "1>\prod", or? - but would tat not be improvable like 1> \alias '\env:@@env@@'='\connect -U sa -S @@env@@ -d mssql-jtds' ===> called "1>\env:prod-db"

regards from Frankfurt,
Matthias

Yes, you are right that the documentation for \alias has a bug in it. It should have just been \prod not \prod-db in the example. I'll fix that.

A command to execute an arbitrary binary should be relatively easy. I'll see if I can take a look at it over the weekend.

I hope all is well!
