A Windows equivalent of the Unix tail command

Question

I m looking for the equivalent of the Unix  tail  command that will allow me to watch the output of a log file while it is being written to

If you do not want to install anything at all you can "build your own" batch file that does the job from standard Windows commands. Here are some pointers as to how to do it.

1) Using find /c /v "" yourinput.file, get the number of lines in your input file. The output is something like:

---------- T.TXT: 15

2) Using for /f, parse this output to get the number 15.

3) Using set /a, calculate the number of head lines that needs to be skipped

4) Using for /f "skip=n" skip the head lines and echo/process the tail lines.

If I find the time, I will build such a batch file and post it back here.

I just wrote this little batch script  It isn t as sophisticated as the Unix  tail   but hopefully someone can add on to it to improve it  like limiting the output to the last 10 lines of the file  etc  If you do improve this script  please send it to me at robbing   at   gmail com    echo off     This is a batch script I wrote to mimic the  tail  UNIX command     It is far from perfect  but I am posting it in the hopes that it will    be improved by other people  This was designed to work on Windows 7     I have not tested it on any other versions of Windows  if   1        goto noarg if   1          goto help if   1      -   goto help if NOT EXIST  1 goto notfound set taildelay  2 if   taildelay       set taildelay 1   loop cls type  1     I use the CHOICE command to create a delay in batch   CHOICE  C YN  D Y  N  T  taildelay  goto loop     Error handlers   noarg echo No arguments given  Try    for help  goto die   notfound echo The file   1  could not be found  goto die     Help text   help echo TAIL filename  seconds      I use the call more pipe as a way to insert blank lines since echo  doesnt    seem to work on Windows 7  call   more echo Description  echo     This is a Windows version of the UNIX  tail  command  echo     Written completely from scratch by Andrey G  call   more echo Parameters  echo    filename             The name of the file to display call   more echo     seconds             The number of seconds to delay before reloading the echo                         file and displaying it again  Default is set to 1 call   more echo                          Displays this help message call   more echo    NOTE  echo    To exit while TAIL is running  press CTRL C  call   more echo Example  echo    TAIL foo 5 call   more echo    Will display the contents of the file  foo   echo    refreshing every 5 seconds  call   more     This is the end   die

I think I have found a utility that meets the need for the tail function in batch files   It s called  mtee   and it s free   I ve incorporated it into a batch file I m working on and it does the job very nicely   Just make sure to put the executable into a directory in the PATH statement  and away you go   Here s the link   mtee

Graphical log viewers  while they might be very good for viewing log files  don t meet the need for a command line utility that can be incorporated into scripts  or batch files    Often such a simple and general-purpose command can be used as part of a specialized solution for a particular environment   Graphical methods don t lend themselves readily to such use
