File size is limited by filesystem type not by OS. Typically, OS supports several filesystems, so there is no such thing like "OS file size limit". There are limits for well-known filesystems:

FAT32 - 4Gib  
NTFS - 16Eib  
ext2/3 - 16Gib - 2Tib (depends from block size)  
ext4 - 16Gib - 16Tib  
XFS - 9Eib  
ZFS - 16Eib

Keep Log File Size Fixed Without Using Logrotate

You could write a little bash script to do this. Just tail the file to a certain byte count using tail -c and overwrite the file.

from man tail:

-c, --bytes=N
              output the last N bytes; alternatively, use +N to  output  bytes
              starting with the Nth of each file

   If  the  first  character of N (the number of bytes or lines) is a `+',
   print beginning with the Nth item from the start of each  file,  other‐
   wise, print the last N items in the file.  N may have a multiplier suf‐
   fix:  b  512,  kB  1000,  K  1024,  MB  1000*1000,  M   1024*1024,   GB
   1000*1000*1000, G 1024*1024*1024, and so on for T, P, E, Z, Y.

Bash – limiting size of logfile from a variable

You need to use logrotate. Do something like this

cat /etc/logrotate.conf

/path/foo.txt {

    size 50M

    create 700 root root

    rotate 5

}

size 50M – logrotate runs only if the filesize is equal to (or greater than) this size.

create – rotate the original file and create the new file with specified permission, user and group.

rotate – limits the number of log file rotation. So, this would keep only the recent 5 rotated log files.
