I have a pattern in a file as follows which can/cannot span over multiple lines :
abcd25
ef_gh
( fg*_h
hj_b*
hj ) {
What I have tried :
perl -nle 'print while m/^\s*(\w+)\s+(\w+?)\s*(([\w-0-9,* \s]))\s{/gm'
I dont know what the flags mean here but all I did was write a regex for the pattern and insert it in the pattern space .This matches well if the the pattern is in a single line as :
abcd25 ef_gh ( fg*_h hj_b* hj ) {
But fails exclusively in the multiline case !
I started with perl yesterday but the syntax is way too confusing . So , as suggested by one of our fellow SO mate ,I wrote a regex and inserted it in the code provided by him .
I hope a perl monk can help me in this case . Alternative solutions are welcome .
Input file :
abcd25
ef_gh
( fg*_h
hj_b*
hj ) {
abcd25
ef_gh
fg*_h
hj_b*
hj ) {
jhijdsiokdù ()lmolmlxjk;
abcd25 ef_gh ( fg*_h hj_b* hj ) {
Expected output :
abcd25
ef_gh
( fg*_h
hj_b*
hj ) {
abcd25 ef_gh ( fg*_h hj_b* hj ) {
The input file can have multiple patterns which coincides with the start and end pattern of the required pattern. Thanks in advance for the replies.
