Better way to do this?

Hi Experts,

After the great suggestions I received yesterday, i'm back again, asking for more Smilie

.
I have close to 8-10 lines of code performing an operation, id like to know, if there is a more compact way to do this.

# Removes the first line which is a message

Code:

awk 'match($0,"The following message") == 0 {print $0}' results_Linux.out > tmp
mv tmp results_Linux.out

# Removes the empty lines in the file

Code:

cat results_Linux.out | awk '$0!~/^$/ {print $0}' > tmp
mv tmp results_Linux.out

# Removes the last part of each line and adds a URL to the end

Code:

sed -e 's|WAITING (Being queued on farm)|http://dte/dte30/faces/monitorPage/jobId=|' results_Linux.out > tmp
mv tmp results_Linux.out

# Adds the first word of each line to the end of the line as well

Code:

awk '{print $0$1}' results_Linux.out > tmp
mv tmp results_Linux.out

# Send a mail to the user

Code:

userID=`whoami`
datetime=`date`
cat results_Linux.out | mail -s "Linux Run Results for - [$userID] executed on - [$datetime]"  $EMAIL

yesterday

YESTERDAY(1)						      General Commands Manual						      YESTERDAY(1)

NAME

       yesterday - print file names from the dump

SYNOPSIS

       yesterday [ -c ] [ -date ] files ...

DESCRIPTION

       Yesterday prints the names of the files from the most recent dump.  Since dumps are done early in the morning, yesterday's files are really
       in today's dump.  For example, if today is March 17, 1992,

	      yesterday /adm/users

       prints

	      /n/dump/1992/0317/adm/users

       In fact, the implementation is to select the most recent dump in the current year, so the dump selected may not be from today.

       With option -c, yesterday copies the dump file to the current directory.

       The date option selects other day's dumps, with a format of 2, 4, 6, or 8 digits of the form dd, mmdd, yymmdd, or yyyymmdd.

       Yesterday does not guarantee that the string it prints represents an existing file.

EXAMPLES

       Back up to yesterday's MIPS binary of vc:

	      cd /mips/bin
	      yesterday -c vc

       Temporarily back up to March 1's MIPS C library to see if a program runs correctly when loaded with it:

	      bind `{yesterday -0301 /mips/lib/libc.a} /mips/lib/libc.a
	      rm v.out
	      mk
	      v.out

FILES

       /n/dump

SOURCE

       /rc/bin/yesterday

       It's hard to use this command without singing.
