Yoda, your answer is not correct; it'll match !/^Date/ in the entire file!
It is necessary to have a kind of state; awk and a state variable is appropriate.
Code:
awk '/^Date/ {s=0} /^Date2;.*;sessionid1;/ {s=1} s' test

nawk or /usr/xpg4/bin/awk.
/bin/awk needs (this time with the OPs input)
Code:
awk '/^Date/ {s=0} /^Date.*;sessionid1;/ {s=1} s!=0' test

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
