Grep a matched line includes below and another matched line includes above
I would like to print a matched line include one line below and another matched line include above.
Here is my file:

Output should be:
$name "path_sparc_ifu_dec_in_1" ;
dtu_inst_d[19] (in) 0.00 0.00 f
ifu_exu_muldivop_d[3] (out) 0.00 1.12 r

I know grep is a tool for this.
grep -A 1 name file.txt
This prints a matched line including below
grep -B 1 critical file.txt
This prints another matched line including above.
But, I don't know how to combine two. Any help is appreciated.
With GNU grep:
grep -Poz --color=never '.*name.*n.*|.*n.*critical.*' file.txt
Output:
$name "path_sparc_ifu_dec_in_1" ; dtu_inst_d[19] (in) 0.00 0.00 f ifu_exu_muldivop_d[3] (out) 0.00 1.12 r critical voltage 1.00838 $name "path_sparc_ifu_dec_in_2" ; dtu_inst_d[21] (in) 0.00 0.00 r ifu_exu_wen_d (out) 0.00 1.11 f critical voltage 1.00275 $name "path_sparc_ifu_dec_in_3" ; dtu_inst_d[22] (in) 0.00 0.00 f ifu_exu_wen_d (out) 0.00 1.10 f critical voltage 1.00174
From man grep :
-P : Interpret PATTERN as a Perl regular expression.
-o : Print only the matched (non-empty) parts of a matching line, with each such part on a separate output line.
-z : Treat the input as a set of lines, each terminated by a zero byte (the ASCII NUL character) instead of a newline
I'm not sure that grep can handle your case, but AWK can:
awk '/name/{print;getline;print}/critical/{print prev;print}{prev=$0}' file.txt
Breakdown:
/name/ { # Match name
print; # Print current line
getline; # Get next line
print; # Print it
}
/critical/ { # Match critical
print prev; # Print previous line
print; # Print current line
}
{
prev = $0 # Store previous line in prev
}
awk来拯救！
$ awk '/$name/{c=2} c&&c--; /critical/{print p; print} {p=$0}' file
$name "path_sparc_ifu_dec_in_1" ;
dtu_inst_d[19] (in) 0.00 0.00 f
