Last time, with the guidance of Climbing, I finally understood the powerful functions of STRINGS. I don't have an English dictionary at hand, so I can only rely on translation software to finally figure out the usage of some sub - commands of STRINGS. Please see the following introduction specifically. Since I don't understand English, if there are any errors or omissions, please help point them out and supplement them. Thank you!!

STRINGS is a very good batch processing enhancement tool. It has many functions, such as character operations, file operations, memory operations, etc., and can output values to target variables. You can enter STRINGS /? in the DOS prompt to view all its usage parameters.

STRINGS/? (View the list of sub - commands of STRINGS)

The following is the list of sub - commands of STRINGS:

LEFT RIGHT MID LENGTH FIND FINDC
LOWER UPPER CHAR VAL FILEDRIVE FILEDIR
FILENAME FILEEXT PARSE ADDCOMMAS REPEAT READ
WRITE FILESIZE LINESIZE TRUENAME FILEDATE FILETIME
VER ASK INWIN 2FCHECK ENVFREE ENVSIZE
MASTERVAR LOCALVAR TRUEVER FILES LASTDRIVE CODEPAGE
COUNTRY BIOSDATE GETKEY LOCALENV MASTERENV ADD
SUB MUL DIV AND OR XOR
NOT CONVERT PEEK POKE IN OUT
INTERRUPT SCAN DAY MONTH DATE TIME
MEMTOTAL MEMFREE XMSTOTAL XMSFREE XMSVER EMSTOTAL
EMSFREE EMSVER UMBLARGE STRINGSVER INSTALLED HELP

To view the help of a specific command, please enter: STRINGS HELP sub - command
For example: STRINGS HELP LEFT (will display the detailed usage of the LEFT sub - command)

The following are the sub - commands that I haven't understood yet. Please supplement their functions if anyone knows. Thank you!!

PARSE 2FCHECK MASTERVAR LOCALVAR LOCALENV MASTERENV XOR

Thank you again, Climbing! Everyone who likes it should give a thumbs up! Hehe!!!

Yeah, it's a great thing, but unfortunately it's not very useful. Still, I have to give it a thumbs up!

That's a good translation. Give it a thumbs up!

Correction:
9. STRINGS [target variable=]CHAR number [number1] [number2]... 〈Convert number to ASCII character〉
10. STRINGS [target variable=]VAL character [character1] [character2]... 〈Convert character to ASCII number〉

Bump up! The character processing ability of pure DOS is relatively weak, and STRINGS can be used as a very good enhancement tool.

STRINGS [variable=] PARSE source string, segment number, delimiter
Returns the character segment with the specified number and delimited by the delimiter
For example: STRINGS PARSE 2007-02-06, 2, - returns 02

Not quite understand, but since I've read it, I should give it a thumbs up.

Thanks to the LZ, looking for the download of STRINGS

Can you give an example to illustrate how to use it?

Support

That's a good translation. I'll also come to support.

Thanks

Great.

But why can't I use this command in my DOS or CMD? Is my version too low, and which command can I use to check?

Additionally, which are the enhanced commands in CMD, and how to install them?
