![]() ![]() e: flag passes the perl script as a parameter i.e perl oneliner. p: Places a print loop around the command. If only 6 groups are used, the 6th capture (seconds) will be checked for a fraction. perl: Denotes pre-defined date and time module. If you're doing something more complex you probably ought to be using one of the modules listed in "SEE ALSO".Īn optional 7th group can be used to capture the fractional seconds. The pattern must capture 6 groups in the appropriate order: year, month, day, hour, minute, second. ![]() The default pattern will match any of the named formats. If the stamp doesn't match the pattern the function will return undef in scalar context or an empty list in list context.Īn alternate regular expression can be supplied as the regexp parameter during import. Typically because I am looking for a jump in the log message times in. I also need to insert timestamp into filname (fileA 12:01:12 fileB 10:50:55 ). Besides Time::Local only takes the first 6 anyway. I have many times needed to calculate the difference between the timestamps in a log file. 25 Mar 07 15:34 Below is script where it edits the file, removes txt extension and writes new file. GUI and programming scripts written in Shell script, Perl, Tcl and Python. NOTE that the wday, yday, and isdst parameters (the last three elements returned from localtime or gmtime) are not returned because they are not easily determined from the stamp. Git is a distributed version control system that tracks changes in any set of computer files. In list context they return the list that would have been sent to Time::Local which is similar to the one returned by gmtime and localtime: seconds, minutes, hours, day, month (0-11), year (-1900). They accept a timestamp and use the appropriate function from Time::Local to turn it back into a seconds-since-epoch integer. Here's an example: writesecs (stat (file)) 9 printf 'file s updated at s ', file, scalar localtime (writesecs) If you prefer something more. T0100 (1:00 AM) Using backticks also works: TIMESTAMPdate. To retrieve the raw'' time in seconds since the epoch, you would call the stat function, then use localtime (), gmtime (), or POSIX::strftime () to convert this into human-readable form. The parser functions are the inverse of the stamp functions. The following Perl scripts correspond to the bash and ksh versions that use sed: (sed. Version 1.300 SYNOPSIS # import customized functions to make easy-to-use timestamps ![]() Time::Stamp - Easy, readable, efficient timestamp functions VERSION ![]()
