some of the lines in a file look like this:
LOB ("VALUE") STORE AS SECUREFILE "L_MS_WRKNPY_VALUE_0000000011"(
LOB ("INDEX_XML") STORE AS SECUREFILE "L_HRRPTRY_INDX_L_0000000011"(
What I can assume is that in the "*"
the string starts with an L_
and ends in 10 chars number.
I want for each line that:
LOB
(white-space before the LOB
) ""
the first two letters are L_
"(
replace the last 10 chars in the ""
with variable.
all I manage to do is: cat /tmp/out.log | sed 's/_[0-9_]*/$NUM/g' > /tmp/newout.log
cat /tmp/out.log | sed 's/_[0-9_]*/$NUM/g' > /tmp/newout.log
to find the required rows I run: grep "^ LOB" create_tables_clean.sql | grep "\\"L_"
grep "^ LOB" create_tables_clean.sql | grep "\\"L_"
However I dont know how to combine the two and get what I wish.
sed -r 's/(\sLOB.*"L_.+_)([0-9]{10})("\()/\1'$myVar'\3/'
Replace $myVar
with your variable, obviously.
I made three capturing groups:
(\sLOB.*"L_.+_) #catches everything until the 10 numbers
([0-9]{10}) #catches the 10 numbers
("\() #catches the last "(
The first capturing group matches only if your line starts with LOB
(with a preceeding whitespace) and contains "L_
.
Then you simply substitute the second capturing group (containing only the 10 numbers) with your variable while keeping the first and third capturing group ( \\1'$myVar'\\3
).
Your whole call would look like
cat /tmp/out.log | sed -r 's/(\sLOB.*"L_.+_)([0-9]{10})("\()/\1'$NUM'\3/g' > /tmp/newout.log
(notice I added the g
-modifier to the regex, so it will match every occurence)
several useless characters are in accepted sed command, here is shorter one.
sed -r 's/(LOB.*"L_.*)([0-9]{10})("\()/\1'$myVar'\3/' file
Second, @Basti M, when you need echo with double quotes in string, use singe quotes, then you needn't escape the double quotes.
echo 'LOB ("VALUE") STORE AS SECUREFILE "L_MS_WRKNPY_VALUE_0000000011"('
