Dear Experts,

On AIX I need to compare 2 files holding percentage space usage:

Format:

hn5691    :   /appli/oltb/apache/logs     72 %
hn5785    :   /appli/logs/REPORTING     38 %
...

If the percentage in the second file is 10% higher than in first file it should write that in a file (so that can be mailed).
Idea is to catch a looping process.

I'm not enough into awk to make it work, your help is appreciated.
I attach 2 files to work with.

Many thanks in advance.

transactions search in unix logs


in the unix logs of transactions each transaction has bunch of values like

transaction_id|transaction_time|transaction_description|transaction_type| ......etc

I created a script that will append a cron job if it's not in the crontab file, but the problem is the appended job will not work unless I edit the crontab file using crontab -e. Is there a way to refresh cron in AIX without killing the process?

difference between double and single quote in unix vs windows word document


1.
grep ‘Bean’ abc_1.log.20180627 //i am able to type this angular single quote in windows laptop in a word pad to save all commands to copy paste to unix box

2.
grep 'Bean' abc_1.log.20180627//why i cannot type this straight single quote character on windows laptop in a word pad to save all commands to copy paste to unix box?
3.
grep "Bean" abc_1.log.20180627


when i type below in word document of windows its shows as

grep ‘Bean’ abc_1.log.20180627
when i type below in putty/mputty of windows its shows as
grep 'Bean' abc_1.log.20180627



my purpose is to save all these unix queries to a word document so that next time i can copy paste from word document to putty and execute them without any tweaking to queries.

Please advise

This is solaris-10 zone and it is repeated issue, I am seeing since sometime. Due to some reason, syslog is holding space and it keeps filling root file-system. I had to nullify process file of syslog and then space consumption of root was reduced from 19 GB to 2.7GB

TSM 7.1 running on AIX 7.1 -Is there a way to restore only the folder structure and not the files within those directories? The restore of Oracle RMAN will populate the directory structures with the files. Thanks in advance!

i would like to know whether any additional slots are available for HBA card in Solaris node (2 Dual port or 1 Quad 4 port HBA). How to check free slots .

1. fcinfo hba-port showing all ports being used
2. luxadm -e port showing one path as not connected .

luxadm -e port

Hi everyone!
I am trying to do a few things in my bash script (script1.sh):  pass logicals/variables to my SAS program (program1.sas), execute SAS code (program1.sas), check with "errstat" for specific errors related to SAS code conditions that I set up in my SAS code, and also check with "logerrchk" SAS log file for any errors in the SAS log.  
I think most of the script is correct but I am not sure about both checking errors (errstat" and "logerrchk").

 Please note: variable/logicals (file1, file2, plog, and errstat) are also defined in the SAS program.  

 Please provide any suggestions or examples if you can.
 Here is what I have so far:

#!/bin/bash
#script1.sh

# Creating variables for directories
export DATADIR1=/root/alldirs/2018/data1
export DATADIR2=/root/alldirs/2018/data2
export DATADIR3=/root/alldirs/2018/data3
export PROGDIR1=/root/alldirs/2018/prog1

#Creating variables for data files that are used in program1.sas and final log file 
export file1=${DATADIR1}/sasdata1.sas7bdat
export file2=${DATADIR2}/sasdata2.sas7bdat
export plog=${DATADIR3}/sas_program.log

#executing SAS program
sas ${PROGDIR1}/program1.sas -log ${DATADIR3}/program1.log

#checking for errors in SAS log file
logerrchk=$?     
   if [[ "$logerrchk" !=0 ]]; 
   then 
       echo "--- Error: Abnormal end in program program1.sas. Check log file! ---" >> $plog
       exit 2
   else
       echo "--- Program1.sas run successfully! ---" >> $plog
   fi
  
#checking for specific errors
