可以替换文件中的文本或者二进制代码中的字节，“-dump”参数可以显示替换前后对比，“-yes”参数加入才会真的替换。

官方例子：

examples
   sfk replace myfile.dat "/Lemon/Curry/"
      replace Lemon by Curry within myfile.dat. search is
      case-insensitive, therefore "lemon" will be replaced as well.
      the quotes "" are optional here.
   sfk replace -pat /FooCase// -dir . -file .txt
      search for FooCase in all .txt files below current directory.
      note that if you leave out the single fileOrDir parameter,
      you have to say -[s]pat, -bin or -text first to tell clearly
      that you will specify the target fileset later on.
   sfk rep -spat "/The foo/The\tbar/" -dir mydocs
      replaces "The foo" by "The" and "bar" separated by TAB char,
      within all files within mydocs.
   sfk rep -binary /1A/20/ -dir docs -file .txt .info .note
      replaces all bytes with code 0x1A by code 0x20, in all .txt,
      .info and .note files, in directory docs and all subdirectories.
   sfk replace tmp\image.dat -bylist patches.txt
      searches for source patterns in file tmp\image.dat,
      replaces by patterns specified in patches.txt
   SFK Base and XE: swap text in two steps
   sfk -yes rep io.txt /foo34/foo99/ /foo12/foo34/ +rep /foo99/foo12/
      replaces foo12 by foo34 and vice versa. with SFK Base, a word
      which is replaced may be replaced again by a following pattern,
      therefore the intermediate step: turn foo34 into something
      not used anywhere in io.txt, then replace foo12, then replace
      the intermediate pattern back in a second replace command
      on the same file.
   SFK XE only: swap text in one step
   sfk rep io.txt /foo12/foo34/ /foo34/foo12/ -yes
      replaces foo12 by foo34 and vice versa. with XE, a word which
      is replaced is not looked at again in the same command, so
      "foo34" from the first pattern is not changed by the 2nd.
   sfk hexfind mydir -pat /FooCase/ +list -late
      do not replace, just find binary files containing "FooCase",
      then list them sorted by time. also accepts -bylist files.
   sfk replace -binary /666f6f/626172/ -dir mydir -file .dat
      replace binary data with hex values 0x66, 0x6f, 0x6f
      by data with values 0x62, 0x61, 0x72 in all .dat files.

example with output:

preparing a replacement of pattern "class Foo".

   sfk rep testfiles "/class foo/class Other/" -dump
