Unix Script - HP-UX

simshark · #1 (**permalink**) 04-09-2008

Guys,

I currently have a script that finds print requests older than 1 day and cancels it from the spooler.

the script goes like this:

###
PRINTERLIST="
hkgwclp0
twapthpc
twapthpb
2o2mlj5d
Itlaser
CIA_Customs
sscopslj9
sscopslj2
sscopslj8
fjnanwp1
phmnl9040"

for PRINTER in $PRINTERLIST
do
find /var/spool/lp/request/$PRINTER -mtime +0
if [ $(find /var/spool/lp/request/$PRINTER -mtime +0 | grep "$LOCAL_SERVER" | wc
-l) -gt 0 ]
then
echo "$PRINTER" >> /cia/ciaadm/bin/printer.list
/usr/local/bin/canprint $PRINTER
let cnt=cnt+1
fi
done
##

this is just a partial script.

i have a few questions:

1. Instead of hardcoding the printer names, how can i just dynamically call the printers from /var/spool/lp/request/$printer-name/?? Is there any other way?
2. How can i break down the find to look for requests older than 1 hour, instead of 1 day?

Sorry im a bit of a N00B....

Thanks all!

If your find is capable enough, it will be able to give you minute granularity. If not, maybe we can develop something here.

If all the entries in /var/spool/lp/requests are the names of printers you want to connect to, and there are none there which you don't want to connect to, just loop over those then?

The wc -l is Useless

Code:

for PRINTER in /var/spool/lp/request/*
do
  if find "$PRINTER" -mmin +60 | grep "$LOCAL_SERVER" >/dev/null
  then
    echo `basename "$PRINTER"` >> /cia/ciaadm/bin/printer.list
    /usr/local/bin/canprint `basename "$PRINTER"`
    let cnt=cnt+1
  fi
done

I guess the cnt is used outside of your script somewhere ...?

era, thanks.

but mmin does not work in my version of hp-ux...im getting a "find bad option - mmin"

I do not want to complicate things by using touch

Is there any other way to break this down?

Thanks!

Pass to Perl, maybe?

Code:

find "$PRINTER" -type f | perl -lne '@s = stat $_; print "$_" if $s[9] < $^T-3600'
