Windows Batch file Dynamic create statements - windows

I need to get a list of file names from a directory using a windows batch program. I would like to take each FILE NAME and combine that with another command line statement.
Note i only need the file name not the contents of the file.
How would this be done?
If i have a 'Data' directory on the D drive with the below files (note there could be many files)
--------------
myFile1.abc
myfile2.abc
------------------
How could i dynamically create something like this using a windows batch program?
move C:\myFile1.abc C:\newdir
move C:\myFile2.abc C:\newdir
note - (i know there is a easier way move files but but i am trying to understand the logic so i can use it in a different command)


You can use a for loop:
for %%X in (D:\*) do (
echo move %%X C:\newdir
)


Try on the command line:
for %X in (D:\DataFiles\*) do echo move "%~fX" C:\newdir>>logfile.txt
It puts all file names from D:\DataFiles in logfile.txt (except hidden files).

Rename multiple files with batch windows

I need to rename a group of .pdf files
In the \Source folder I have the files:
bbbbbbbbb-56.pdf
vduysdvss-60.pdf
sdvbdsbvv-80.pdf
I have to rename them in the \Destination folder like this:
11111111-bbbbbbbbb-ggg-hhh-56-dddd.pdf
11111111-vduysdvss-ggg-hhh-60-dddd.pdf
11111111-sdvbdsbvv-ggg-hhh-80-dddd.pdf
so I need to insert some fixed parts:
before the name
in the middle of the name
at the end of the name.
Using the command:
cd \Source
copy "\Source" "\Destination"
cd \Destination
ren *.pdf 11111111-?????????-ggg-hhh???-dddd.*
the result is:
11111111--56-ggg-hhh-dddd.pdf
the bbbbbbbbb string disappears
can you help me?
Thanks

By using the following command Copy the files from Source to Destination :
copy "/Source_folder" "/Destination_folder"
Go in /Destination folder
cd "/Destination_folder"
And then ren the file names by the following command :
ren *.pdf ???-new_filename_part.*
(The question mark (?) is also a wildcard, but it represents a character of the original file name. So, in the syntax, we're using three question marks, which means that the output file name will include the first three characters of the original file (which works as a unique identifier to avoid duplication)
(According to your logic you can change the new filenames by using some RegExpressions or some variables)

Using a batch file, how can I rename this file?

I'm having issues renaming the following file using a batch (.bat) file. I'm using Windows 7.
Here's my syntax:
SET MY_PATH=%~dp0
ren %MY_PATH%\MY_RECAP* DBS.txt
I'm attempting to rename a file that has a changing file name due to the current date being appended to the end of the MY_RECAP file name (such as MY_RECAP_MMDDYYYY). I'm using a wildcard to rename that file to DBS.txt
This still won't work. Any ideas?

There are quite many solutions to do this. The first and easier one is:
#ren "%~dp0MY_RECAP_*" "DBS.txt"
If you want to check a DBS.txt file already exists, use an if exist statement:
#if not exist "%~dp0DBS.txt" (#ren "%~dp0MY_RECAP_*" "DBS.txt")
An additional note: If in your batch file you have specified somewhere above #echo off or echo off, remove the # symbols from everywhere.

Windows batch - concatenate multiple text files into one

I need to create a script, which concatenates multiple text files into one.
I know it's simple to use
type *.txt > merged.txt
But the requirement is to "concatenate files from same day into file day_YYYY-DD-MM.txt" I am a Linux user and Windows batch is hell for me. It's Windows XP.

Windows type command works similarly to UNIX cat.
Example 1: Merge with file names (This will merge file1.csv & file2.csv to create concat.csv)
type file1.csv file2.csv > concat.csv
Example 2: Merge files with pattern (This will merge all files with csv extension and create concat.csv)
When using asterisk(*) to concatenate all files. Please DON'T use same extension for target file(Eg. .csv). There should be some difference in pattern else target file will also be considered in concatenation
type *.csv > concat_csv.txt

At its most basic, concatenating files from a batch file is done with 'copy'.
copy file1.txt + file2.txt + file3.txt concattedfile.txt

In Win 7, navigate to the directory where your text files are. On the command prompt use:
copy *.txt combined.txt
Where combined.txt is the name of the newly created text file.

Place all files need to copied in a separate folder, for ease place them in c drive.
Open Command Prompt - windows>type cmd>select command prompt.
You can see the default directory pointing - Ex : C:[Folder_Name]>.
Change the directory to point to the folder which you have placed files to be copied, using ' cd [Folder_Name] ' command.
After pointing to directory - type 'dir' which shows all the files present in folder, just to make sure everything at place.
Now type : 'copy *.txt [newfile_name].txt' and press enter.
Done!
All the text in individual files will be copied to [newfile_name].txt

I am reiterating some of the other points already made, but including a 3rd example that helps when you have files across folders that you want to concatenate.
Example 1 (files in the same folder):
copy file1.txt+file2.txt+file3.txt file123.txt
Example 2 (files in same folder):
type *.txt > combined.txt
Example 3 (files exist across multiple folders, assumes newfileoutput.txt doesn't exist):
for /D %f in (folderName) DO type %f/filename.txt >> .\newfileoutput.txt

We can use normal CAT command to merge files..
D:> cat *.csv > outputs.csv

cat "input files" > "output files"
This works in PowerShell, which is the Windows preferred shell in current Windows versions, therefore it works. It is also the only version of the answers above to work with large files, where 'type' or 'copy' fails.

Try this:
#echo off
set yyyy=%date:~6,4%
set mm=%date:~3,2%
set dd=%date:~0,2%
set /p temp= "Enter the name of text file: "
FOR /F "tokens=* delims=" %%x in (texto1.txt, texto2.txt, texto3.txt) DO echo %%x >> day_%temp%.txt
This code ask you to set the name of the file after "day_" where you can input the date.
If you want to name your file like the actual date you can do this:
FOR /F "tokens=* delims=" %%x in (texto1.txt, texto2.txt, texto3.txt) DO echo %%x >> day_%yyyy%-%mm%-%dd%.txt

You can do it using type:
type"C:\<Directory containing files>\*.txt"> merged.txt
all the files in the directory will be appendeded to the file merged.txt.

copy is definitely much faster than type - but it sometimes (with large files?) adds a SUB character at the end of the file. So, strictly speaking, it does not simply concatenate the files in the same way as cat in Unix.
So, the correct answer is to use cat - either in something like Git Bash (where it has the same syntax as in Unix), or PowerShell (where it does not).

Renaming files of variable length in DOS

I'm trying to rename files that have '#' to '_'.
I understand that there is a straigt forward way of replacing the nth character in a file.
How do we rename files , if # symbol is present in different places in different files
For example, assuming the below files are present in a directory
a#file.txt
asdf#kfi.png
uiuydfjfk#kdi.txt
I want the output to be like this one
a_file.txt
asdf_kfi.png
uiuydfjfk_kdi.txt
Is there anyway to accomplish this ?

This uses a helper batch file called repl.bat from - http://www.dostips.com/forum/viewtopic.php?f=3&t=3855
It creates renfile.bat for you to examine for errors, and then execute.
dir *#* /b |repl "(.*)(#)(.*)" "ren \x22$&\x22 \x22$1_$3\x22" x >renfile.bat

How to continuously run a exe within a batch file with different parameters

I have an exe application that takes in 2 parameters. One is a input file path with an specific extension (e.g. *.jpg) and Second is the output file path.
Now in a folder, I have let's say 100 jpeg images which I want to pass in continuously and saved the output with the same file name as the input (extension will be different, the exe does the conversion).
Any idea how do I write a batch file to achieve this?
Thanks and Regards,
Perumal

Try this:
#FOR %%1 IN (%1) DO convert %%1 %2\%%n1.png
To be used as:
bulkconvert c:\test\*.jpg c:\test
It'll call convert for each file that matches the search pattern c:\test*.jpg and a 2nd parameter will be provided with the path provided as batch's 2nd parameter (note: there is not the trailing backslash) with the same file name but with extension png.
