I Love Linux Lets say we need to print only strings between two lines that contain patterns ‘BEGIN’ and ‘END’. Print Lines Between Two Patterns with SED With thesedcommand, we can specify thestarting pattern
Note the space between the two remembered patterns. This is used to make sure two words are found. However, this will do nothing if a single word is found, or any lines with no letters. You may want to insist that words have at least one letter by using sed 's/\([a-z][a-z]...
下面的例子会删除在”ONE”和”TWO”之间的字符,如果它们没有相邻的两行。 #!/bin/sh sed ' /ONE/ { # append the next line N # look for "ONE" followed by "TWO" /ONE.*TWO/ { # delete everything between s/ONE.*TWO/ONE TWO/ # print P # then delete the first line D } }' file...

The ‘sed‘ command, short for stream editor, is a versatile and powerful text manipulation tool that operates on text streams, allowing users to perform various operations on data, such as search, replace, insert, and delete. ‘Sed’ uses regular expressions to define patterns for text manipul...
