[grep awk cut] > awk

Hi, I'm very new to scripting. grep $s $filename | awk '{print $2}' | cut -c 1-8 How can I optimize this using a single awk? I tried: awk '/$s/ {print $2}' $filename | cut -c 1-8 However didn't work, I think the awk is not recognizing $s and the verbal is something else.

Is it better to grep and pipe to awk, or to seach with awk itself

This may just be a lack of experience talking, but I always assumed that when possible it was better to use a commands built in abilities rather than to pipe to a bunch of commands. I wrote a (very simple) script a while back that was meant to pull out a certain error code, and report back what...

ncab2clf

ncab2clf(1)							   User Commands						       ncab2clf(1)

NAME

       ncab2clf - convert binary log file to Common Log File format

SYNOPSIS

       /usr/bin/ncab2clf [-Dhv] [-i input-file] [-o output-file] [-b size] [-n number] [-s datetime]

DESCRIPTION

       The  ncab2clf command is used to convert the log file generated by the Solaris Network Cache and Accelerator ("NCA") from binary format, to
       Common Log File ("CLF") format. If no input-file is specified, ncab2clf uses stdin. If no output-file is specified, the output goes to std-
       out.

OPTIONS

       -b	       Specifies the binary-log-file blocking in kilobytes; the default is 64 Kbyte.

       -D	       Specifies that direct I/O be disabled.

       -h	       Prints usage message.

       -i input-file   Specifies the input file.

       -n number       Output number CLF records.

       -o output-file  Specifies the output file.

       -s datetime     Skip  any records before the date and time specified in datetime. You can specify the date and time in CLF format or in the
		       format specified by the touch(1) utility. CLF format is the dominant format, so ncab2clf first analyzes	datetime  assuming
		       CLF.

       -v	       Provides verbose output.

EXAMPLES

       Example 1: Converting a Binary File to a Common Log File Format

       The following example converts the binary file /var/nca/logs/nca.blf to a file /var/nca/logs/nca.clf, which is in Common Log File format.

       example% ncab2clf -D -i /var/nca/logs/nca.blf -o /var/nca/logs/nca.clf

       Example 2: Converting Multiple Log Files

       The following script may be used to convert multiple log files. The directory designated by "*" must only contain log files.

       !/bin/ksh
       for filename in *
       do
	   ncab2clf -D < $filename > $filename.clf
       done

       Example 3: Using -s and -n on a Raw Device

       The  following  example	shows  how ncab2clf can be used on a raw device. If not using the -n option, the default is to convert all records
       from the starting location to the end of the file. The date and time specified with -s, below, is in CLF format.

       example% ncab2clf -s '10/Apr/2001:09:23:13' -n 100 < /dev/dsk/c2t1d0s6

EXIT STATUS

       The following exit values are returned:

       0	       The file converted successfully

       >0	       An error occurred.

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:

       +-----------------------------+-----------------------------+
       |      ATTRIBUTE TYPE	     |	    ATTRIBUTE VALUE	   |

       |Availability		     |SUNWncau			   |
       +-----------------------------+-----------------------------+
       |Interface Stability	     |Evolving			   |

NOTES

       The binary log files generated by NCA can become very large. When converting these large binary files, use the -b option  to  the  ncab2clf
       command to help performance.

       Direct  I/O is a benefit to the user if the data being written does not come in as large chunks. However, if the user wishes to convert the
       log file in large chunks using the -b option, then direct I/O should be disabled by using the -D option.
