parsing text with spaces?


L

LWG

I am trying to find a way to parse the output from an arcserver command. The
command basically dumps the tapes loaded in the 40 available slots. The
output follows: (btw this is only 5 of the 40 slots)

SLOT NAME ID SEQ. SERNO LOADED WP
1 <<Cleaning Cartridge>> 0000 0 -- --
2 BD8671L1 7f4a 1 BD8671L1 NO NO
3 BD8698L1 902a 4 BD8625L1 NO NO
4 6/19/04 5:50 PM bf50 1 BD8568L1 NO NO
5 9/24/04 6:47 PM b49d 1 BD8975L1 YES NO

the columns are sorted like:
slot name id seq. serno loaded wp

the diffuculty is when there are spaces in the name. The slot 1 has the
cleaning cartridge which has no serial number and creates another porblem.
What I want as an ouput is the slot and serno columns. So it would look
like:

1 bd8569l1
2 bd8975l1
3 bd1234l1
4 bd3338l1...

Thx for the help in advance...

Read with a for and use set to extract the data from offset, length

@echo off
setlocal
for /f "delims=" %%A in ('findstr "YES NO" ^<infile.txt'
) do call :sub "%%A"
goto :eof
:sub
set line=%~1
set SLOT=%line:~0,2%
set SERNO=%line:~43,8%
echo %SLOT% %SERNO%

Untested!

I have to say this worked, if you have moment could you explain from this
point?

for /f "delims=" %%A in ('findstr "YES NO" ^<infile.txt'> ) do call :sub
"%%A"

1. correct me if I am wrong- for read in infile.txt and scans for yes no
then?
2. goto :eof?
3. set line=%1 ?
4.set slot=?
5.set serno?

btw, this worked with nothing other than me changing the file from
infile.txt to myname.txt.

thank you,
Larry

I don't understand the question.
2. goto :eof?
CMD's way for a QUIT command. See "GOTO /?".
3. set line=%1 ?
4.set slot=?
5.set serno?
See "SET /?" and "FOR /?".

I used findstr to filter the relevant lines which contain either YES or
NO. The for iterates through the output of findstr reading the whole
lines into %%A, instructed by the "delims=" *not* to split into args.

I used an internal sub to ease the following positional extraction (An
alternative is to use delayed expansion possible from w2k or newer).

The call :sub with quoted "%%A" is necessary to pass the line as one
argument. The arguments passing is the same as with external batches,
the first arg being %1.
2. goto :eof?
Leave the batch, an alternative would be: exit /B 0
3. set line=%1 ?
In fact it is "set line=%~1" to put the content with removed outmost
quotes into the environment variable line
4.set slot=?
set SLOT=%line:~0,2%
gets two places from offset zero into env var SLOT
5.set serno?
set SERNO=%line:~43,8%
gets eight places from offset 43 into env var SERNO

I'm just glad you didn't ask for this :)
echo %SLOT% %SERNO%

Fine, you are able to tweak that and use batch tricks in future. For
details on the used commands follow my signature and Michaels suggestion.
