Shell Programming and Scripting

I have an inpit file that looks like the following:
VDL20039 [CDL_L700_LIB: 40] VPROD 12/23/05 20:01:07 198713.31 198713.31 11/25/05

I'm currently using this command, which seem to work fine
cat VPROD|awk 'BEGIN {i=1} {while (i <= 4){if($8 == $9){print "\t"$3,$4; ++i}getline}}'|cut -c 17-18`

Which end result is just the 40

A command line string that resembles
omnimcopy -src_slot

My question is I want to preceed each line with the above

omnimcopy -src_slot 40
omnimcopy -src_slot 41
omnimcopy -src_slot 42

How do I do something like this using awk?

Try this; there is no need to use cut, and awk loop, and getline:

Code:

nawk '$7 == $8 {
    gsub(/]/,"",$3)
    print "omnimcopy -src_slot "$3
}' VPROD

Your example shows $7 equaling $8 so I used those instead of $8 and $9

or slightly different:

Code:

nawk -F '([]]| )' '$8 == $9 {print "omnimcopy -src_slot " $3}' VPROD

1st replay works fine,although I get an extra line at the end
omnimcopy -src_slot
Not needed

2nd cmd $4 should be the output , but it's not.

Really helpful

My whole goal is to get a string that follows:

omnimcopy -from Some_Drive -src_slot Source data -slot Target_slot -copy Target_Drive -label Header_Infor -until expiration
SOURCE_DR=`/usr/sbin/mc -p /dev/rac/c13t0d0 -r D|awk '{if($2 == "EMPTY") {gsub("DT_slot","VTAKSSAP1_LTO2",$1) gsub("EMPTY","");printf("%
14s", "omnimcopy -from " $1"\n")}}'`
SOURCE_SL=`cat VPROD|awk 'BEGIN {i=1} {while (i <= 4){if($8 == $9){printf("%9s", " -src_slot " substr($4,1,length($4)-1)"\n"); ++i}getli
ne}}'`
TARGET_DR=`/usr/sbin/mc -p /dev/rac/c11t12d0 -r D|awk '{if($2 == "EMPTY") {gsub("DT_slot","TAKSSAP1_LTO2",$1) gsub("EMPTY","");printf("%
7s", " -copy " $1"\n")}}'`
TARGET_SL=`omnimm -list_scratch TAK_PROD|grep LSLMSL1|awk 'BEGIN {i=1} {while (i <= 4){printf("%7s", " -slot " $5"\n"); ++i getline}}'`
POOL=`echo " -pool TAK_PROD \n"`
LABEL=`omnimm -list_scratch TAK_PROD|grep LSLMSL1|awk 'BEGIN {i=1} {while (i <= 4){printf("%8s", " -label " $3"\n"); ++i getline}}'`
PROTECTION=`cat VPROD|awk 'BEGIN {i=1} {while (i <= 4){if($8 == $9){printf("%8s", " -until " $6"\n"); ++i}getline}}'`

echo "$SOURCE_DR\t\t$SOURCE_SL\t\t$TARGET_DR\t\t$TARGET_SL\t\t$LABEL\t\t$PROTECTION\n"


I know it's really not ledgeable , but the intent is to get the following:
omnimcopy -from -src_slot -copy -pool -until

HELP

here's the cleaned-up version of one of your lines. See if you can clean up and debug the rest of them:

Code:

#!/bin/ksh

SOURCE_SL=$(awk 'FNR <= 4 && ($8 == $9) {printf(" -src_slot %s ", substr($4,1,length($4)-1))}' VPROD)

The following is the output I am try'ing to achieve, although there several
command issue'd to get the out. I would like to somehow get this info
line by line.

-src_slot 18
-src_slot 40
-src_slot 37
-src_slot 4
-copy TAKSSAP1_LTO2_3 -slot 40
-slot 42
-slot 39
-slot 38 -label LD0288L2
-label LD0295L2
-label LD0282L2
-label LD0219L2 -until 12/23/05
