.SH "NAME"
replace \- a string\-replacement utility
.SH "SYNOPSIS"
.HP \w'\fBreplace\ \fR\fB\fIarguments\fR\fR\ 'u
\fBreplace \fR\fB\fIarguments\fR\fR
.SH "DESCRIPTION"
.PP
The
\fBreplace\fR
utility program changes strings in place in files or on the standard input\&.
.if n \{\
.sp
.\}
.RS 4
.it 1 an-trap
.nr an-no-space-flag 1
.nr an-break-flag 1
.br
.ps +1
\fBNote\fR
.ps -1
.br
.PP
The
\fBreplace\fR
utility is deprecated as of MySQL 5\&.7\&.18 and is removed in MySQL 8\&.0\&.
.sp .5v
.RE
.PP
Invoke
\fBreplace\fR
in one of the following ways:
.sp
.if n \{\
.RS 4
.\}
.nf
replace \fIfrom\fR \fIto\fR [\fIfrom\fR \fIto\fR] \&.\&.\&. \-\- \fIfile_name\fR [\fIfile_name\fR] \&.\&.\&.
replace \fIfrom\fR \fIto\fR [\fIfrom\fR \fIto\fR] \&.\&.\&. < \fIfile_name\fR
.fi
.if n \{\
.RE
.\}
.PP
\fIfrom\fR
represents a string to look for and
\fIto\fR
represents its replacement\&. There can be one or more pairs of strings\&.
.PP
Use the
\fB\-\-\fR
option to indicate where the string\-replacement list ends and the file names begin\&. In this case, any file named on the command line is modified in place, so you may want to make a copy of the original before converting it\&.
\fIreplace\fR
prints a message indicating which of the input files it actually modifies\&.
.PP
If the
\fB\-\-\fR
option is not given,
\fBreplace\fR
reads the standard input and writes to the standard output\&.
.PP
\fBreplace\fR
uses a finite state machine to match longer strings first\&. It can be used to swap strings\&. For example, the following command swaps
a
and
b
in the given files,
file1
and
file2:
.sp
.if n \{\
.RS 4
.\}
.nf
replace a b b a \-\- file1 file2 \&.\&.\&.
.fi
.if n \{\
.RE
.\}
.PP
\fBreplace\fR
supports the following options\&.
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3
.\}
\fB\-?\fR,
\fB\-I\fR

Display a help message and exit\&.

.sp

.ie n \{\

.el \{\

.IP \(bu 2.3

\fB\-#\fR\fB\fIdebug_options\fR\fR
.sp
Enable debugging\&.
