The replace utility program changes strings in place in files or on the standard input.
The replace utility is deprecated as of MySQL 5.7.18 and is removed in MySQL 8.0.
Invoke replace in one of the following ways:
to] ... --
to] ... <
from represents a string to look for
to represents its replacement.
There can be one or more pairs of strings.
-- 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
replace prints a message
indicating which of the input files it actually modifies.
-- option is not given,
replace reads the standard input and writes
to the standard output.
replace uses a finite state machine to match
longer strings first. It can be used to swap strings. For
example, the following command swaps
b in the given files,
replace a b b a -- file1 file2 ...
replace supports the following options.
