Shell Programming and Scripting

Hello,

I run this command from a solaris box and it works just fine. It gives me the kind of output in my file I am looking for which would be for example...

sb1p
rdop
ot2p
ot3p
eimp


However when I do the same thing from a Linux box...

ps -ef | grep nco_p_syslog | grep -v grep | awk '{print $NF}' | awk -F. '{print $1}' > $OMNIHOME/bin/syslogfile.dat


I get this in the file...
/lcl/apps/Tivoli/netcool/omnibus/probes/linux2x86/syslog


Both are using
#!/bin/ksh


I have no idea where it is even getting that long directory path from for the results.

Any ideas?

Thanks in advance.

It's differences between the output of solaris ps and linux ps. You'll probably have to make modifications with allowances for the different OSes. You could probably do some case switching magic to do it all in one script, though.

Anyway, I don't have access to a solaris box at the moment, so my suggestion is to start with the base command and work down from there, adding on the pipes one at a time until you figure out where the difference is.

Do:

ps -ef | grep nco_p_syslog

on both, then compare the output. If you don't understand what each command does, you should spend some time reading the various manual pages until you do.

Ok I have been trying that and did some reading up on awk however I can not seem to find how to only capture the last part.

Currently I do...

Code:

ps -ef | grep nco_p_syslog | grep -v grep | awk '{print $NF}' | awk -F. '{print $1}' > $OMNIHOME/bin/syslogfile.dat

Which gives the results of....

Code:

/lcl/prd/data/dc000p/dump/bdump/alert_dc000p

I only want the dc000p part to record to the dat file.
For the life of me I can not seem to figure out the awk commands to do that.

Any help would be great also explaining how the awk would work how its being used above. I am very new to it and the stuff I am reading is a bit confusing so far.

I am sooo close!!!

I am now doing this...

Code:

ps -ef | grep nco_p_syslog | grep -v grep | awk '{print $NF}' | awk -F_ '{print $2}' >> $OMNIHOME/bin/syslogfile.dat

Which gives this result....

Code:

dc000p.log

I just can not figure out how to cut the .log from the end :-(

Why not

Code:

ps -ef | awk -F. '/nco_p_syslog/ { print $NF }' > $OMNIHOME/bin/syslogfile.dat # Solaris
ps -ef | awk -F'_' '/nco_p_syslog/ { print substr($NF, 1, index($NF, ".")-1) }'  > $OMNIHOME/bin/syslogfile.dat # Linux

Hhhhmmm that gives me this result...

Code:

syslog/ { print substr($NF, 1, index($NF, "
dc000p

I only want to capture the dc000p part.

Without trying very hard:

ps -ef | grep nco_p_syslog | grep -v grep | awk '{print $NF}' | awk -F_ '{print $2}' | cut -d '.' -f 1

Maybe? I don't have your output.
