Thanks Corona688 for the information.

I didn't understand completely, can you try replacing those ? with . (period) if echo "$z" | grep -q "R1......R1";

Something like this..?
michaelf>uname
SunOS
michaelf>nawk -F'[: ]' '/Parameter Name/{f=$5;getline;print f"-->"$5}' infile
SNAPSHOTTIMESTAMP-->2014-01-07-15.21.50.022423
DATABASESIZE-->96178176...

Alternate Sed..
$ sed 's/\([^ ]*\) \([^ ]*\) \(.*\).$/\1 \2 \3_\1_\2"/' inputFile
chr1 + "NM_1234_chr1_+"
chr1 - "NM_1234_chr1_-"
$

If you want to reproduce sed's + character to * then try as below
sed 's/@[a-z0-9A-Z][a-z0-9A-Z]*\.[a-zA-Z0-9][a-zA-Z0-9]*/REPLACE/g'

Replace with the below sed in the loop and try..
sed 's/k/'$i'/g' inputfile

I do get the expected output as mentioned in post #1 with the same input file pattern. Can you attach the large file that does not work for these solutions..?
$ sed 's/^ *//
> /PRODUCT CODE/{
> :l...

Alternate awk..
$ uname -rs
SunOS 5.10
$ nawk '$6!="9999"{gsub(/[)(\]\[]/,"",$0);print}' inputfile

Try the below as is..
$ uname -rs
SunOS 5.10
$ sed 's/^ *//
> /PRODUCT CODE/{
> :l
> N
> /<.PRODUCT>/{
> s/ *\n *//gp
> d
> }
> bl
> }' inputfile

It does not require any change to run in a shell script, just copy paste the sed or awk lines into a file and run. But remember to give full path name of the inputfile, its better coding.
$ cat...

Through Sed..
sed -n 'H;/^$/{x;/COMMAND.*SEARCHPATTERN/s/.*\(REQUESTSTRING[^;]*\);.*/\1/p}' inputfile

Through Sed..
sed 's/^/000/' inputfile

I neither worked in Postgres or installed it in my pc to test hence i would not able to help you much, but try searching in internet for postgres sql tuning tips etc. As suggested earlier try...

Or try..
awk '{a[$0]++;next}END{for(i in a)print i,a[i]}' filename

Through Sed
sed 's/\([^,]*,[^,]*,\)\([^ ]*\) \([^,]*\),\([^ ]*\) \([^,]*\)/\1\3 \2,\5 \4/' inputfile

To the test file you have posted above, try something like..
sed '/ARS (11)/!s/.*/SOME TEXT HERE\n&/' test_file
Note: This would not work for all scenarios until there is a exact sample input/test...

Command cut would do the same job
echo $str | cut -d'|' -f1 # try -f2 or -f3

I guess this kind of output is something related to OS. What OS your in..? Try mailx's -a option to send attachment if available

What OS your using..? Maybe you can try as Len=`/usr/local/bin/expr "$BASENAME" : '.*'` instead of length expression.

Here you go..
[mkt@michael]$ sed '/^<li>/{
> />$/!s/$/<\/li>/
> }' inputfile
...
<li>keyword</li>
<li>keyword</li>
<li>keyword</li>
<li>keyword</li>
<li>keyword</li>
...
[mkt@michael]$...

Remove the s in sed command and try, s is for substitute but here you only delete.
sed '/^\.abc/d' inputfile

# General solution..
sed '/^\./d' inputfile

You would need to remove the control character \r present near $1 either by running
$ tr -d '\r' < mc.sh > mc_new.sh
$ ./mc_new.sh
# or if you have the dos2unix utility then
$ dos2unix mc.sh >...

You can try -r alpha@domain.com along with the mail command. But check in your man page as different OS would have their own meanings.

Ok.Since you do not pass any input to awk statement you just get the output as File Owner. Try as suggested by itkamaraj or ls -l | ./awk_example1.sh

How do you run the above awk script..? Try like sh awk_example1.sh where
[mkt @michael]$ cat awk_example1.sh
#!/bin/sh
# Linux users have to change $8 to $9
awk '
BEGIN { print "File\tOwner" }...
