I am trying to replace a string in multiple lines. It is late and I'm getting restless, maybe someone would prefer to give it a shot for some SO points. The string I'm replacing is 'STORED AS TEXTFILE' from the SQL below...
PARTITIONED BY(load string, date string, source_file string)
STORED AS TEXTFILE
LOCATION '${staging_directory}/${tablename}';
And to make it look like...
PARTITIONED BY(load string, date string, source_file string)
ROW FORMAT DELIMITED
FIELDS TERMINATED BY ','
STORED AS TEXTFILE
LOCATION '${staging_directory}/${tablename}';
So my expression is
:%s/)\nSTORED AS TEXTFILE\nLOCATION '/)\rROW FORMAT DELIMITED \rFIELDS TERMINATED BY ',' \rSTORED AS TEXTFILE \rLOCATION '/g
Which works inside the file (with vim) but I can't get it to work with one command on all of the files in the directory. I've tried so far...
sed -i "s/)\nSTORED AS TEXTFILE\nLOCATION '/)\rROW FORMAT DELIMITED \rFIELDS TERMINATED BY ',' \rSTORED AS TEXTFILE \rLOCATION '/g"
... and I also tried the above statement with all the spaces escaped. Please help!
gawk in-place editing approach - available since GNU awk 4.1.0:
gawk -i inplace '$0~/STORED AS TEXTFILE/{ $0="ROW FORMAT DELIMITED" ORS "FIELDS TERMINATED BY \047,\047" ORS $0 }1' file*
-i inplace
- in-place editing of each input file sed processes file line by line following link gives a solution for multiline processing https://unix.stackexchange.com/questions/26284/how-can-i-use-sed-to-replace-a-multi-line-string
otherwise in perl the default input line separator $/
can be changed or undefined (read whole file):
perl -i.BAK -pe 'BEGIN{undef$/}s/.../.../g' file
After reading comments on accepted answer of link, GNU sed has the -z
option which does quite the same uses NUL character as line delimiter ( $\\="\\0"
), whereas undef $/
uses no delimiter.
