Download program or batch file	Operating system	Description
LogTextSetup.exe LogText.zip Version from 2006-11-03	Windows (95/98/ME/ NT/2000/XP)	Logtext is a command line utility that logs text lines into log files. A date and time stamp according to ISO8601 including a time zone offset precedes each logged line, which is written into a file with the given name. Depending on the parameters, the log files' names can be appended by the current year (yyyy), the current month (yyyy-mm), the current week (yyyy-Wcw), or the current day (yyyy-mm-dd). The utility can automatically handle old log files and process them accordingly, i.e. either delete or compress them by using the gzip library. Additionally a logfile can be rotated by its file size or the number of text lines it contains. Another feature is that the program can read the text to log from standard input, hence you can log the entire output of console programs or batch files. Examples: logtext batchname "We want to log this text." ECHO This example adds a text line to the file named 'batchnameyyyy-mm-dd.log' in the current directory. The content of the line is 'yyyy-mm-dd +/-timezone We want to log this text.', where yyyy represents the current year, mm means the current month, dd refers to the current day of month, and timezone is the time difference to UTC (Coordinated Universal Time) in 4 digit ISO format. The parameter ECHO specifies that the text shall be sent to the standard output as well. No log file will be deleted or compressed.   logtext batchname "We want to log this text." ECHO MONTHLY This writes into a file called 'batchnameyyyy-mm.log'. The content of the text line remains the same.   logtext batchname "We want to log this text." ECHO 10 Creates a new log file daily, but only keeps the files of the last 10 days. Older files are automatically deleted.   logtext batchname "We want to log this text." ECHO 10 10 Keep the log files of the last 10 days. Additionally, keep another 10 logfiles in a compressed (gzip) form, i.e. this invokation keeps 10 days alltogether, 10 in plain text, the other 10 packed. Even older files are automatically deleted.   logtext c:\windows\logfiles\batchname "We want to log this text." ECHO 2 20 Put the log files into the folder c:\windows\logfiles, keep 2 uncompressed and 20 compressed log files.   logtext %SystemRoot%\batchname "We want to log this text." ECHO 2 20 Automatically obtain the system directory from the command interpreter and put the log files there.   batch.cmd | logtext %SystemRoot%\batchname_ "This text is ignored." ECHO STDIN 2 20 Log the output (no errors) of the command line job batch.cmd into %SystemRoot%\batchname_yyyy-mm-dd.log.   batch.cmd  2>&1| logtext %SystemRoot%\batchname_ "This text is ignored." ECHO STDIN 2 20 Log all output (standard and errors) of the command line job batch.cmd into %SystemRoot%\batchname_yyyy-mm-dd.log. Another good example on how to use the logtext utility is the DeleteTempFolder script.   Notes: Here is one of the silliest questions I've heard about the logtext utility: "How can I change the date/time format to mm/dd/yy?" Smart answer: If you don't want to have date and time in ISO8601 format, either use another utility like logtime, which is part of the Windows Ressource Kits and might be found somewhere on the net, or discontinue using local date/time notations at all. You also might want to have a look at  Implementation of the ISO 8601 Standard Around The World. Even smarter answer: A particular date in England was 05/11/2000. Apparently, it looks like an American would have celebrated Bonfire Night in May. Cheers. Any additional questions why logtext uses the ISO8601 notation? Better not.
