Ok, you can do it with awk as this example:
Code:
$ DATETIME="28-Sep-2013;20:09:08;"
$ CONTROL="AB"
$ echo "Myfile.txt|11671|7824.90|tttt|2822.48|xxx|yyy" | awk -F'|' -v d=$DATETIME -v c=$CONTROL 'BEGIN{OFS=";";} {print d$1,c,$2,$3,$5;}'
28-Sep-2013;20:09:08;Myfile.txt;AB;11671;7824.90;2822.48

Beware: you must concat variable d and $1 because end d is already ";"

Otherwise, technically, it's possible with shell solution but most slow:
Example:
Code:
$ echo "Myfile.txt|11671|7824.90|tttt|2822.48|xxx|yyy" | ( IFS=\| read a b c d e f g; echo "$DATETIME$a;$CONTROL;$b;$c;$e")
28-Sep-2013;20:09:08;Myfile.txt;AB;11671;7824.90;2822.48

NAME
igawk - gawk with include files SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ... igawk [ all gawk options ] [ -- ] program-text file ... DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1). AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like @include getopt.awk in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path. OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports. EXAMPLES
cat << EOF > test.awk @include getopt.awk BEGIN { while (getopt(ARGC, ARGV, "am:q") != -1) ... } EOF igawk -f test.awk SEE ALSO
