How to Insert a line after a pattern and insert another line before the first occurence of a word from...
sub tc1 {
a
b
c
d
endcase
}
sub tc2
{
a
b
c
endcase
}
I want to call a subroutine say start() after sub tc1 and call stop() before that endcase of sub tc1
I used this command
perl -i.bak -pe 'BEGIN{undef $/;} s/(subs+TC1[sn]+{)(.*)endcase/$1n&start();$2&stop();nendcase/smg' file.txt
Output
sub tc1 {
&start();
a
b
c
d
endcase
}
sub tc2
{
a
b
c
stop();
endcase
}
but it is modifying at lastly matched endcase pattern
Expected output
sub tc1 {
&start();
a
b
c
d
&stop();
endcase
}
perl sed

This should be easy task of awk
, could you please try following if you are ok with awk
.
awk '
/sub tc1/{
sub_tcl_val=$0 ORS "&start();"
flag=val=""
next
}
/endcase/ && ++count==1{
flag=1
print sub_tcl_val ORS val ORS "&stop()" ORS $0 ORS "}"
val=sub_tcl_val=""
next
}
!flag{
val=val?val ORS $0:$0
}' Input_file
Output will be as follows.
sub tc1 {
&start();
a
b
c
d
&stop()
endcase
}
But if I have lines before sub tc1 it is appending those lines after start();

This might work for you (GNU sed):
sed -e '/sub tc1/,/endcase/!b;/sub tc1/a&start();' -e '/endcase/i&stop();' file
Use a range to focus on the start/end delimiters in this case sub tc1
/endcase
. Then append the string &start();
after the start delimiter and insert the string &stop();
before the end delimiter.
$ sed -e '/sub tc1/,/endcase/!b;/sub tc1/a&start();' -e '/endcase/i&stop();' myfil sed -e '/sub tc1/,/endcase/bvi;/sub tc1/a&start();' -e '/endcase/i&stop();' myfil sed: can't find label for jump to `vi'

This might work for you (GNU sed):
sed -e '/sub tc1/,/endcase/!b;/sub tc1/a&start();' -e '/endcase/i&stop();' file
Use a range to focus on the start/end delimiters in this case sub tc1
/endcase
. Then append the string &start();
after the start delimiter and insert the string &stop();
before the end delimiter.
$ sed -e '/sub tc1/,/endcase/!b;/sub tc1/a&start();' -e '/endcase/i&stop();' myfil sed -e '/sub tc1/,/endcase/bvi;/sub tc1/a&start();' -e '/endcase/i&stop();' myfil sed: can't find label for jump to `vi'
