Redirecting 'memlimits' into a file

Michael Steele_2 — Fri, 21 Jul 2006 10:45:37 GMT

hello there..

anyone ever try to redirect /usr/sap//SYS/exe/run/memlimits >> outfile?

a) won't redirect
b) output still is written to screen
c) fills outfile with control chars.
d) vi outfile results in 'line too long' error
e) fold -s oufile works but is full of control chars.

comments?

The problem is memlimits won't write to outfile when directed from a script and continues to write to the screen.

I suspect that SAP is helping you out by always writing on /dev/tty. It is also possible that they are writing to a file descriptor greater than 2 (stderr); a run under tusc would tell you which file descriptor is being used.

I suggest that you minimize the number of extraneous characters by setting and exporting TERM=dumb.

That helped a great deal in the sense that outfile filled with readable ascii chars top and bottom which provided me with the info I was seeking but still through in a bunch of control chars that I'm going to have to filter out at a latter time.

Thanks again Clay.

If you set TERM=dumb (and assuming that SAP doesn't have its own terminal database) then you should have very few control-characters. You could pipe the output through this filter to only allow printable ASCII, LF, FF, and through.

memlimits | tr -cd "[ -~\n\t\f]" > outfile

When I try this I get white space, carriage returns and 2 sets of dashed lines. Using : | tr -cd "[ -~\n\t\f]" produced similar results filtering regular expressions like :graph:, :print:, :alnum:, etc.

thanks !

Hi,

you can filter many 'motion escapes' out with col -bx

(see man page).

Hey, that worked just fine!

# memlimits | col -bx > outfile

Many Thanks!
