disk space utilization script

Shell Programming and Scripting

Hi,

I wrote the following script for monitoring disk space and inform the concerned team accordingly. But script gives me below error

syntax error at line 70 : `<' unmatched

#!/bin/ksh

What's your input file look like? Does this happen on every line of input?

Hi,

My input file (integration_services.txt) look like this:

Intg_Svc01 /d1/Intg_Svc01 83886080
Intg_Svc02 /d2/Intg_Svc02 167772160
Intg_Svc03 /d3/Intg_Svc03 83886080
Intg_Svc04 /d4/Intg_Svc04 83886080

Yes it greps for each line of input and get the value in 2nd and 3rd column from above file.

Likely to be due to this line:

The "!" at the end of your "here" document MUST be in column one. Is is indented in error.

5

More precisely, that '!' must be either in column one or preceded by tabs in your script. There are likely some spaces characters instead of tabs before the '!'.

The ending string must start in column one when <<string is used, <<-string allows indentation.

6

Btw. If I run in validation only mode with "ksh -n" my error message is:

syntax error at line 46 : `<<' unmatched

No idea where the posted error came from.

Well spotted jlliagre .
The error is indeed cleared by removing all spaces from the line containing the terminating "!" line or replacing those spaces with one or more tabs.

Thanks everyone. I have actually changed the mailx command. I gave something like this and it worked.

echo "email body" | mailx -s "Email notification of Integration Service direcroty exceeding defined threshold" ${alertlist}
