.TH SYSCTL.CONF "5" "2021-09-15" "procps-ng" "File Formats"
|
|
.SH NAME
|
|
sysctl.conf \- sysctl preload/configuration file
|
|
.SH DESCRIPTION
|
|
.B sysctl.conf
|
|
is a simple file containing sysctl values to be read in and set by
|
|
.BR sysctl .
|
|
The syntax is simply as follows:
|
|
.RS
|
|
.sp
|
|
.nf
|
|
.ne 7
|
|
# comment
|
|
; comment
|
|
|
|
token = value
|
|
.fi
|
|
.RE
|
|
.PP
|
|
Note that blank lines are ignored, and whitespace before and after a token or
|
|
value is ignored, although a value can contain whitespace within. Lines which
|
|
begin with a \fI#\fR or \fI;\fR are considered comments and ignored.
|
|
|
|
If a line begins with a single \-, any attempts to set the value that fail will be
|
|
ignored.
|
|
|
|
.SH NOTES
|
|
As the
|
|
.BR /etc/sysctl.conf
|
|
file is used to override default kernel parameter values, only a small number of parameters is predefined in the file.
|
|
Use
|
|
.IR /sbin/sysctl\ \-a
|
|
or follow
|
|
.BR sysctl (8)
|
|
to list all possible parameters. The description of individual parameters can be found in the kernel documentation.
|
|
|
|
Maximum supported line length of the value is 4096 characters due
|
|
to a limitation of \fI/proc\fR entries in Linux kernel.
|
|
