Top Forums Shell Programming and Scripting Split and add header and trailer from input file Post 302905114 by Chubler_XL on Monday 9th of June 2014 06:26:11 PM

Can you supply a demo of the input file with this new line characters, are you talking about blank/empty lines?

To explain the new code:

Code:
    -v f="TOM PAT SAM BOB KIM" \
    -v t="TOM TOM TOM BOB KIM" '
BEGIN {
   split(f,from)
   for(i=split(t,to);i;i--) CONV[from[i]]=to[i]
}

Above we pass into awk two space separated lists f and t (for from and to). These are loaded into a CONV lookup array. Such that:
Code:
CONV[TOM] => TOM 
CONV[PAT] => TOM
CONV[KIM] => KIM

Below we check the line and if it's setup in the CONV array we assign the fname and write the header line to the file when this is the first time this file is written. If line is not setup in CONV array fname is "xyz_error_" plus time-stamp instead:

Code:
   if (typ in CONV) {
       fname="xyz_" CONV[typ] "_" stamp ".txt"
       if (!(fname in A)) {A[fname]; print header > fname}
   } 
   else fname="xyz_error_" stamp ".txt"

NAME
uuencode - format of an encoded uuencode file DESCRIPTION
Files output by consist of a header line followed by a number of body lines, and a trailer line. The command ignores any lines preceding the header or following the trailer (see uuencode(1)). Lines preceding a header must not look like a header. The header line consists of the word followed by a space, a mode (in octal), another space, and a string which specifies the name of the remote file. The body consists of a number of lines, each containing 62 or fewer characters (including trailing new-line). These lines consist of a character count, followed by encoded characters, followed by a newline. The character count is a single printing character, which represents an integer. This integer is the number of bytes in the rest of the line, and always ranges from 0 to 63. The byte count can be determined by subtracting the equivalent octal value of an ASCII space charac- ter (octal 40) from the character. Groups of 3 bytes are stored in 4 characters, 6 bits per character. All are offset by a space to make the characters printable. The last line may be shorter than the normal 45 bytes. If the size is not a multiple of 3, this fact can be determined by the value of the count on the last line. Extra meaningless data will be included, if necessary, to make the character count a multiple of 4. The body is terminated by a line with a count of zero. This line consists of one ASCII space. The trailer line consists of the word on a line by itself. SEE ALSO
