A large file needs to be processed to delete the contents before the matching string in each line. The file content format is as follows:
aaa dd kk segmentfault=1098-0987-3jlc ok=okj hello=0cvqa 12jk od=kk segmentfault=1jj8-lk87-oplc suiji=che shachu=keng pppp=dd bbo; =9as segmentfault=0876-oj87-3pac zifu=ka neirong=xia
It is expected that the contents before the first occurrence of segmentfault in each row can be deleted to the beginning of the row, and the expected processing results are as follows
segmentfault=1098-0987-3jlc ok=okj hello=0cvqa segmentfault=1jj8-lk87-oplc suiji=che shachu=keng segmentfault=0876-oj87-3pac zifu=ka neirong=xia
Use macros to execute
Qa-start macro recording /resourceid-do whatever you want D0-operate at will and delete to the beginning of the line. J-operate at will and jump to the next line. Q-exit macro 1000000@a --- 1000000 executions
Disadvantages: Low efficiency and extremely time-consuming
It is expected to delete the matching position of each row to the beginning of the row after direct column editing (ctrl+v).
How should this be achieved?
Try regular replacement, column editing, your keyword position is different, direct column editing is not possible
