i have series of files want clean .log files have been rotated. examples: error.log access.log error.log-2016-02-05 access.log.1 debug.log debug.log--2 regex matching of log files with: find . -regextype posix-extended -regex '^.*.log.*' how can match files have characters after *.log? replace last occurrence of .* .+ . * matches 0 or more instances of previous character. + matches 1 or more instances. you need escape . before log \ , otherwise match character rather literal period. in summary, use this: find . -regextype posix-extended -regex '^.*\.log.+' a few other adjustments might useful: you don't want match files empty filenames, should switch first .* .+ (thanks, jan!). you don't want allow files file extension .log. (a single . character after .*log ), should switch final .+ \..+ . this give final command: find . -regextype posix-extended -regex '^.+\.log\..+'
