 |
|
Hi
I'd like to know how to rename a file to itself, just adding the current date as a suffix, without using AHK. I mean, in the command line itself.
Like:
| Code: | | ren C:\test\test.txt C:\test\test_23-2-10__02-12.txt |
I Googled a bit, and found some weird and complicated stuff, which didn't work in here I don't know why:
and
Please help!

found this , worked for me with date
http://www.computerhope.com/issues/ch000987.htm
see delimiter, token , variables d e f
xy.bat=
| Code: | for /f "tokens=1-3 delims=." %%d in ("%date%") do rename "hope.txt" hope_%%d-%%e-%%f.txt
pause
|
| Quote: |
for /f "tokens=1-5 delims=/ " %%d in ("%date%") do rename "hope.txt" %%e-%%f-%%g.txt
* for /f - The for command and the /f switch.
* "tokens=1-5 delims=/ " - How many tokens the incoming data (in this case the date) will be broken into; 1-5 is five different tokens. Finally, delims is short for delimiters and is what is used to break up the date, in this example the / (forward slash) and a space (space before the quote).
* %%d - The beginning character used for the token. Since there are 5 tokens in this example it would be d,e,f,g, and h.
* in ("%date%") - The data being used, in this case the %date% is the current date of the computer.
* do - What the for command will do. The rename command can be substituted for anything else.
* rename "hope.txt" %%e-%%f-%%g.txt - rename the file "hope.txt" to the tokens e,f, and g with a .txt file extension. This example also has a - (hyphen) in-between each token to separate the month, day, and year in the file name.
When %date% is used in a batch file it displays the date in the following format: Sun 09/02/2007 this command breaks this date into the tokens: "Sun" (%%d), "09" (%%e), "02" (%%f), and "2007" (%%g).
In this example using the above date mentioned hope.txt would be renamed to 09-02-2007.txt.
Time
for /f "tokens=1-5 delims=:" %%d in ("%time%") do rename "hope.txt" %%d-%%e.txt
This command is very similar to the above example. However, instead of using the forward slash and space to break up the data we're using a : (colon) because the time is split up with this character. Finally, because we're renaming the file to only the hour and minute this example is only using the d and e token. Additional information about what everything in this line means is found in the above date example.
When %time% is used in a batch file it displays the time in the following format: 19:34:52.25, this command breaks this time into the tokens: "19" (%%d), "34" (%%e), and "52.25" (%%f).
In this example using the above time mentioned hope.txt would be renamed to 19-34.txt.

Well, thanks! But so far it didn't work..
Does the fact that I didn't use a batch file, but the command line directly interfere? I tried both examples and from both I got this message returned: "%d was unexpected at this time".
Why?

Humm, indeed! Except that the output format is:
test_20100223203227.txt ! How to make the format neat but preserving the A_now function?

can also use a loop to rename all files or all files.txt
| Code: | ;-- rename file C:\test\test.txt
A=%A_now%
stringmid,YY,A, 1,4
stringmid,MM,A, 5,2
stringmid,DD,A, 7,2
stringmid,HR,A, 9,2
stringmid,MI,A,11,2
AA=_%DD%-%MM%-%YY%__%HR%-%MI%
F1=C:\test\test.txt
SplitPath,F1, name, dir, ext, name_no_ext, drive
F2=%dir%\%name_no_ext%%aa%.%ext%
filemove,%F1%,%F2%
ifexist,%dir%
run,%dir%
return
|
rename all text files in c:\test
| Code: | gosub,time1
FOLD=c:\test
Loop, %fold%\*.txt, 0, 1
{
SplitPath,A_LoopFileFullPath,name, dir, ext, name_no_ext, drive
F2=%dir%\%name_no_ext%%aa%.%ext%
filemove,%A_LoopFileFullPath%,%F2%
}
ifexist,%fold%
run,%fold%
return
time1:
A=%A_now%
stringmid,YY,A, 1,4
stringmid,MM,A, 5,2
stringmid,DD,A, 7,2
stringmid,HR,A, 9,2
stringmid,MI,A,11,2
AA=_%DD%-%MM%-%YY%__%HR%-%MI%
return
