Hi All.
I have a file that contains some special characters and I'm trying to use AWK to search for lines between <pattern1> and <pattern2>.
As an example:
I need the lines between the line containing ' select_id="x_0 ' and the line containing the next instance of ' from '. This is a file called 'x.txt':
If I use the following then I get the output I need :
(with the double quote escaped.)
However - the first search pattern might change so I need to pass that to awk as a variable.
E.G.
But this works to match the first pattern using similar syntax.
srvr#
q_db_task=1000, select_id="x_0", text=" select ",
I think I fixed it using awk in a script :
BUT - Any help to understand why the pattern match doesn't work would be much appreciated.

Code:
srvr# awk -v sqry='select_id=\\"x_0' '/sqry/,/from/' x.txt
awk: syntax error near line 1
awk: bailing out near line 1
and same using nawk returns nothing.
srvr# nawk -v sqry='select_id=\\"x_0' '/sqry/,/from/' x.txt

nawk -v sqry='select_id=\\"x_0' '$0 ~ sqry' x.txtI think I fixed it using awk in a script :
Code:
BEGIN {awkvar2=sqry;awkvar3="from"}
($0 ~ awkvar2),($0 ~ awkvar3)
