The following batch processing files implement the function of replacing strings in a specific file type in a specified directory. Although you can write a statement in Unix or Linux, it is easier to use batch processing in Windows than to compile a program. Reference @ Echo off Setlocal Rem dpath: Specifies the Directory Rem filetype: Specifies the file type. Rem scontent: replace the previous string Rem DContent: string after replacement Rem tmpfile: Temporary File Set dpath = C:/test Set filetype = *. txt Set scontent = aaa Set DContent = bbb Set tmpfile = % random %. tmp For/R % dpath % I in (% filetype %) Do ( If exist % tmpfile % (DEL/f/Q % tmpfile %) For/F "tokens = *" % J in (% I) Do ( Set TMP = % J Echo! TMP: % scontent % = % DContent %! >>% Tmpfile % ) Move/Y % tmpfile % I ) Endlocal Save the preceding content as replace. bat, and then run CMD/V: On/C replace. bat on the command line. In this example, AAA in all TXT files in the C:/test directory (including sub-Directories) is replaced with BBB.

TMP: % scontent % = % DContent %! >>% Tmpfile % "what does it mean? The replaced files are all like this: ! TMP: AAA = BBB! ! TMP: AAA = BBB! ! TMP: AAA = BBB! --- Ph4nt0m Security Team Http://ph4nt0m.org/

If anyone is interested, they can continue to improve or explore new features. As for the content replaced by zzzevazzz, the system I use is 2000 and I don't know what you are. If your system is also 2000, you can refer to the CMD and set commands help to view the content about the delayed environment variable. Do not forget to add the/V: On parameter of CMD while executing the BAT file. I have never tried other systems. I think all systems later than 2000 will have this feature. In addition, if I have tried it myself, I will not send it, but I still want to thank you because you have pointed out the problem for me. Learn from you at the same time because of your rigorous attitude towards things.

TMP: % scontent % = % DContent %! >>% Tmpfile % Unnecessary spaces are added before ">" of this statement. The file name with spaces is easy to solve. The following is what I modified: @ Echo off Setlocal Rem dpath: Specifies the Directory Rem filetype: Specifies the file type. Rem scontent: replace the previous string Rem DContent: string after replacement Rem tmpfile: Temporary File Set dpath = C:/test Set filetype = *. txt Set scontent = aaa Set DContent = bbb Set tmpfile = % random %. tmp For/R % dpath % I in (% filetype %) Do ( If exist % tmpfile % (DEL/f/Q % tmpfile %) For/F "usebackq tokens = *" % J in ("% I") Do ( Set TMP = % J Echo! TMP: % scontent % = % DContent %!> % Tmpfile % ) Move/Y % tmpfile % "% I" ) Endlocal --- Ph4nt0m Security Team Http://ph4nt0m.org/

You can solve the problem by using the following methods: Echo! TMP: % scontent % = % DContent %!> Nul 1> % tmpfile % There is also a space problem in the file name. Your processing method is good and you fully utilize the usebackq feature. It can also be used as an alternative: For/F "tokens = *" % J in ('Type "% I.

If the text contains ^ & ":; <> these characters are difficult to process No function dedicated to character and string operations, no multi-thread performance, no read/write memory.
