Hi Brother,

I would like to ensure the print queue is "0" before dayend, how can I create script to check it? exp using lpstat ...etc. May I have sample? I try to write the sample but hard to search the number of job in lpstat.

Thanks

You could do this two ways:  count the number of files in the spool directory or parse the output of lpstat.

By examples...

On my AIX test system I print to a file in dev directory as my printer/queue.  My jobs live in this directory:

/var/spool/lpd/qdir

I submitted a job and held it with enq -H x.x

enq -H x.x

Here it is in the queue...

root@josephgr josephgr] lpstat
Queue   Dev   Status    Job Files              User         PP %   Blks  Cp Rnk
------- ----- --------- --- ------------------ ---------- ---- -- ----- --- ---
ascii   print READY    
              HELD        3 x.x                root                   1   1   1
 

Parsing lpstat output

The magic is this command....

lpstat | egrep -v "^Queue|^----|^ascii"              #I strip the header and the queue name

[root@josephgr josephgr] lpstat | egrep -v "^Queue|^----|^ascii"
              HELD        3 x.x                root                   1   1   1

In a script you could do...

if [[ `lpstat | egrep -v "^Queue|^----|^ascii" | wc -l | tr -d ' '` = 0  ]]
then  
        "no jobs"
else
        echo "I got jobs"
 fi

By counting spool directory for files....

The key commands is this...

ls |  wc -l | tr -d ' '

Spool...

[root@josephgr josephgr] ls -l /var/spool/lpd/qdir
total 8
-rw-rw----   1 root     printq         1539 Jul 23 14:47 n0root:ascii$#@!tZEb

In a script...

if [[ `ls |  wc -l | tr -d ' '` = 0  ]]
then  
        "no jobs"
else
        echo "I got jobs"
 fi
