Here is a suggestion:
Code:
$ echo $file_name1
RYK11603_PLK5692601_RKYADAV_RHGT_GHTH.PDF
$ echo $file_name1 | sed "s/\(.*\)_PLK\([0-9]*\)_.*/\1_\2.pdf/"
RYK11603_5692601.pdf

@tadavricky. I tried you original solution on Solaris 10 and it worked without a hitch..
As an alternative you could try:
Code:
printf "%s\n" "${file_name1}"| awk -F'[-~_][A-Z]*' '{sub(/.*#/,x); print $1=$1 "_" $2 tolower ($3)}'

On Solaris use /usr/xpg4/bin/awk

@Scrutinizer thanks for reply
here is the one more strange thing

If we run the below command on HP UX it gives output as below which is i need
Code:
export var1=myguidelines
export var1_upper=MYGUIDELINES
i=pk#RYK30213_MYGUIDELINES_PAPER.PDF
file1=$(echo ${i}| cut -d"#" -f2|  sed "s/\([!-~]*\)_${var1_upper}_\([!-~]*\).PDF/\1_${var1_upper}.pdf/")
echo $file1

output :RYK30213_MYGUIDELINES.pdf
output Needed:RYK30213_MYGUIDELINES.pdf


If we run the command on LInux the out is not correct.
Code:
export var1=myguidelines
export var1_upper=MYGUIDELINES
i=pk#RYK30213_MYGUIDELINES_PAPER.PDF
file1=$(echo ${i}| cut -d"#" -f2|  sed "s/\([!-~]*\)_${var1_upper}_\([!-~]*\).PDF/\1_${var1_upper}.pdf/")
echo $file1

Output: RYK30213_MYGUIDELINES_PAPER.PDF
output Needed: RYK30213_MYGUIDELINES.pdf

it would be good learning if you can find the reason. also please help to correct the sed

---------- Post updated at 05:45 PM ---------- Previous update was at 05:25 PM ----------

export var1=myguidelines
export var1_upper=MYGUIDELINES
i=pk#RYK30213_MYGUIDELINES_PAPER.PDF
file1=$(echo ${i}| cut -d"#" -f2| sed "s/\([^-~]*\)_${var1_upper}_\([^-~]*\).PDF/\1_${var1_upper}.pdf/")
echo $file1
output: RYK30213_MYGUIDELINES.pdf

i=pk#RYK30213_MYGUIDELINES_PAPER_RFR_PF.PDF
file1=$(echo ${i}| cut -d"#" -f2| sed "s/\([^-~]*\)_${var1_upper}_\([^-~]*\).PDF/\1_${var1_upper}.pdf/")
echo $file1
output/ RYK30213_MYGUIDELINES.pdf

The out is correct after i replace the ^ with !

do we have any explaination why?

Thanks for all your help and input, last answer i look is why?

Try:
Code:
printf "%s\n" "${i}"| cut -d"#" -f2| sed "s/\([[:punct:][:alnum:]]*\)_${var1_upper}_\([[:punct:][:alnum:]]*\)\.PDF/\1_${var1_upper}.pdf/"

It finally dawned on me that [!-~] is of course the range of ascii printable characters between ! and ~ Smilie, and that probably this will give different results, depending on locale settings.
