Also, specify the name of the file that contains the text. 'the last newline is trimmed' incorrectly implies that command substitution trims at most one trailing newline, when, in reality, 'sequences of one or more characters at the end of the substitution' are removed.
I am answering this portion very reluctantly, upon request from OP.Īny future reader, Don't parse ls, use globbing. To search for text pattern in a file, simply run grep followed by the pattern name. $ ls -1 supports this natively: file1(|]|]]) Process a binary file as if it were text this is equivalent to the -binary-filestext option. Places a line containing - between contiguous groups of matches. If you only meant to match any characters between a-z and A-Z, use use character class which denotes all alphabetic characters in the current locale: $ ls -1 Print NUM lines of trailing context after matching lines. ![]() Does it work for /path/to/file with spaces. You need to add a + after the s to indicate that you want to match at least one spaces as apposed to exactly one space. In bash, using extglob pattern (should be enabled by default in interactive sessions, if not do shopt -s extglob to set it first): matched any single character, selects any of the patterns separated by |. If you have multiple spaces between text then you will get blank lines.
