Shell Programming and Scripting

Hey,

Each night, about 2000 network devices are being backupped. So in different folders, i've got each night 2000 new text files.
And normally, in these files, on the last 5 lines, the word 'end' or 'return' should be found. If not, it means that the backup failed.

Is there an easy way (script) to check the files if these words are on the last 5 lines?
A kind of output in a log file would be great...


Thanks!

The tail command is your friend

Code:

$tail -f file1 file2 file3

Otherwise look for a tool named multitail to tail multiple files.

Something like:

Code:

for file in *.txt
do
   tail -5 $file | grep -E "end|return" > /dev/null 2>&1
   if [ $? -ne 0 ]
   then
      echo $file failed
   fi
done

Carlo,

This works perfect...



The end result:

Code:

 CURRENT_DATE=$(date '+%Y%m%d)

for file in /backups/*/$CURRENT_DATE/*.txt
do
   tail -5 $file | grep -E "end|return" > /dev/null 2>&1
   if [ $? -ne 0 ]    
   then
      echo $file failed >> /var/log/backups/checks/$CURRENT_DATE.log    
   fi
done

Maybe an extra check that i don't have to check manually the log files, but this helps me already a lot...
