You can also use ls with grep, and use grep s pattern matching capabilities. To list files that have '.c' extensions, use this format: ls.
I am answering this portion very reluctantly, upon request from OP.Īny future reader, Don't parse ls, use globbing. To list any files or directories that have names starting with 'ip' use this format: ls ip.
#LS GREP PRESERVE NEWLINE HOW TO#
$ ls -1 supports this natively: file1(|]|]]) How to preserve newline characters in grep result Ask Question Asked 12 years, 5 months ago Modified 1 year, 1 month ago Viewed 23k times 36 I want to assign the grep result to a variable for further use: lines (cat abc.txt grep 'hello') but seems newline characters are removed in the result, when I do echo lines only one line is printed. 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 I understand this happens because every command is executed in a subshell, and thus cd Downloads & ls is executed in a subshell of its own and then the output (namely the list of stuff I have) gets redirected via the pipe to grep.
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 |.
