Sort by absolute value
Hi,
I have a file as follows:
Code:
  |-30.0|Appls. executing in db manager currently   = 2
  |-80.0|Locks held currently                       = 1
  | 90.0|High water mark (bytes)                 = 65536
  |-50.0|Configured size (bytes)                 = 16777216
  |-100.0|Current size (bytes)                    = 131072

I want to sort on the absolute value of the second column with '|' as delimeter. sort -n sorts the field numerically but cannot sort by its absolute value ignoring the signs.

I would like to get an output as follows:
Code:
  |-30.0|Appls. executing in db manager currently   = 2
  |-50.0|Configured size (bytes)                 = 16777216
  |-80.0|Locks held currently                       = 1
  | 90.0|High water mark (bytes)                 = 65536
  |-100.0|Current size (bytes)                    = 131072

Please help.

Thanks,
Sudha

	   There were problems encountered when the kernel was writing the logfile.  The most common problem is running out of disk space.

       invalid log file

	   The logfile is not a valid logfile or was created with a newer version of Solaris than the one where cachefswssize is running.
