Shell Programming and Scripting

Length of each valid record in the above example and solution by vgersh is 73,
In my original file it is 1700 and 1699. any record of length 1700 or 1699 is valid and need not be processed.

vgersh,

output from the modified file is 0 records, it is skipping all the rows in the file.
Also as I mentioned a valid record can have 1700 or 1699 as length and starts from length 16 onwards.
-any length shorter than this is problematic, i.e, record is divided.
- any record starting in less than 16 is continuation of previous.

The first code worked for records broken to two, but there are records broken to three too.
If you can tweak the code again will be great.[COLOR="#738fbf"]

there's no 'tweaking' needed:

nawk -v len=1700 -f enigma.awk myFile

enigma.awk:

Code:

BEGIN {
  len=(!len)?73:len
}
length < len {
   if (length(s)) { s=s OFS $0}
   else s=$0
   if (length(s) == len) { print s; s=""}
   next
}
