Function
compress This is used to compress the rotated log file with gzip.
nocompress This is used when you do not want to compress rotated log files.
copytruncate This is used when processes are still writing information to open log files. This option copies the active log file to a backup and truncates the active log file.
nocopytruncate This copies the log files to backup, but the open log file is not truncated.
create mode owner group This rotates the log file and creates a new log file with the specified permissions, owner, and group. The default is to use the same mode, owner, and group as the original file.
nocreate This prevents the creation of a new log file.
delaycompress When used with the compress option, the rotated log file is not compressed until the next time it is cycled.
nodelaycompress This overrides delaycompress. The log file is compressed when it is cycled.
errors address This mails logrotate errors to an address.
ifempty With this, the log file is rotated even if it is empty. This is the default for logrotate.
notifempty This does not rotate the log file if it is empty.
mail address This mails log files that are cycled to an address. When mail log files are cycled, they are effectively removed from the system.
nomail When mail log files are cycled, a copy is not mailed.
olddir directory With this, cycled log files are kept in the specified directory. This directory must be on the same filesystem as the current log files.
noolddir Cycled log files are kept in the same directory as the current log files.
prerotate/endscript These are statements that enclose commands to be executed prior to a log file being rotated. The prerotate and endscript keywords must appear on a line by themselves.
postrotate/endscript These are statements that enclose commands to be executed after a log file has been rotated. The postrotate and endscript keywords must appear on a line by themselves.
daily This is used to rotate log files daily.
weekly This is used to rotate log files weekly.
monthly This is used to rotate log files monthly.
rotate count This specifies the number of times to rotate a file before it is deleted. A count of 0 (zero) means no copies are retained. A count of 5 means five copies are retained.
tabootext [+] list This directs logrotate to not rotate files with the specified extension. The default list of extensions is .rpm-orig, .rpmsave, v, and ~.
size size With this, the log file is rotated when the specified size is reached. Size may be specified in bytes (default), kilobytes (sizek), or megabytes (sizem).
