Hi Panyam,

We have huge files to work upon and looking for a faster and better way other than converting each character to its ascii value.Also, the record layout changes when we try your command which would give incorrect position. To mention all the files will consist of fixed length records

Is there a way where we can run grep using the ascii value of this special character directly? Is there any better way to do this?We will just need to locate this special character and find the number of occurrences,number of records its impacting and the fields impacted based on the position.Any help on this is highly appreciated.

Thanks for replying.

strsetup

strsetup(8)						      System Manager's Manual						       strsetup(8)

NAME

       strsetup - STREAMS setup and information command

SYNOPSIS

       /usr/sbin/strsetup [-cdfi]

OPTIONS

       Lists  the  current  kernel  configuration of STREAMS modules and devices. Any user can run the strsetup -c command.  Deletes all character
       special files listed in the configuration file that do not map to currently configured STREAMS drivers.	Specifies a file that contains the
       specifications  to  build  third  party or installation-specific character files for STREAMS-based drivers.  It uses the same specification
       format as the strsetup.conf file.  Creates the STREAMS-based special files appropriate for  your  kernel  configuration.   By  default  the
       strsetup  command uses the information in the /etc/strsetup.conf file to build the STREAMS-based special files with the correct names, file
       permissions, and minor numbers.	If the strsetup.conf file does not exist, the strsetup command defaults to creating clone  character  spe-
       cial files.

	      The strsetup -i command is run automatically at boot time.

DESCRIPTION

       The  strsetup  command displays the setup of your STREAMS modules and creates the appropriate character special files for the STREAMS-based
       drivers in your kernel configuration.

FILES

       Default directory in which the -i option creates the pseudodevices

SEE ALSO
