Shell Programming and Scripting

Dear All PROs

Thanks in advance

need a shell for Decimal to hex conversion

input file (decimal values)

65,5,48,66,133,131,118,47
65,5,48,66,133,131,83,63
.
.


desire output should be (Hex value)

41,5,30,42,85,83,76,2F
41,5,30,42,85,83,53,3F
.
.
.

one thing more
where there is single value i need to append 0

exact desired OUT should be like this

41,05,30,42,85,83,76,2F
41,05,30,42,85,83,53,3F
.
.
.
.

please note : input file has 500k entries

Thanks a lot

is it a home work ?

use below

Code:

perl -wlanF',' -e 'foreach $x (@F) { $_ =~ s/$x/uc(sprintf("%02x",$x))/egi };print ;' infile.txt

use this code

decimal --> replace with your file name

Code:

 awk -F"," '{ for(i=1;i<=NF;i++) printf("%.2x,",$i);printf("\n")}' decimal | tr "[:lower:]" "[:upper:]" | sed s/.$//

Bundle of thanks for you guys
