Re: QSH Command Format

Hi Jack

The command she used on the interactive shell command line worked. In that case, all that is needed is to quote the quote. In CL, that quote is actually an apostrophe. I feel I must challenge you on the "...appalling range of CL escape quote mechanism...". Personally, I found the back-tick mechanism to be curious, but then I didn't grow up in Unix or Linux, that came later.

All languages and formats deal with whatever quotation mark is used with some kind of escaping - whether doubling it or using an escape character, often a backslash. Typical again is CSV, where a quotation mark within in a string is doubled - that's the same technique as used in CL, with __its__ quotation mark.

The IBM i __can__ be helpful with quoting the quote - in commands with character parameters, when you prompt the command, simply enter the string without leading quotes but include the embedded ones - the system automagically makes it the right thing.

Admittedly, this does get messier when doing expressions in CL programs. And in RPG it is highly recommended, IMO, to have a variable or constant named, say, QT which is declared as '''' - that's 4 apostrophes/single quotes.

And when I said "...final apostrophe..." - an apostrophe is the same as a "single" quote. I assume, with the usual risk :) , that this was understood by the OP, et al.

Vern

Vernon, she was missing the final quote but also I think it was barfing on
the $( ... ) syntax (parentheses).

Me not knowing the full and appalling range of CL escape quote mechanisms
:), it looks simpler to use back-tick `command ...` syntax.

Hi

I don't think you need the full quotes. You didn't need them in the
interactive sessions.

And you are missing a final apostrophe.

Hope this helps

Hello List,

Can anyone tell me the format needed to put the following command in a

CLP?

It works fine in an interactive session. (It copies the existing file

and inserts the current date in the file name.)

This works in an interactive session:
cp /GSAcct/CHKSALAP.PDF chksalap_$(date '+%Y-%m-%d').pdf


This is NOT working in my CLP:
ADDENVVAR ENVVAR(QIBM_QSH_CMD_OUTPUT) VALUE(NONE) +
LEVEL(*JOB) REPLACE(*YES)

QSH CMD('cp /GSAcct/CHKSALAP.PDF "chksala_$(date ''+%Y-%m-%d'').pdf")


Thank you,
