isDir equivalent in cmd - powershell

I'm using tshell to connect to a device and I need to check if a given path is a file or directory.
I was hoping to use the cmd-device function which runs cmd commands on the device, but there doesn't seem to be a cmd command to do this.
Does someone have a way to check whether a given path is to a directory or to a file using the standard cmd functions?

Since you have PowerShell tagged in your question, one option would be to check the object type returned by the Get-Item cmdlet.
(Get-Item C:\Windows) -is [System.IO.DirectoryInfo]
# Shorter version
(gi C:\Windows) -is [IO.DirectoryInfo]

The usual test for a folder existence is
if exist "x:\somewhere\" echo FOLDER FOUND
but, in some cases (i know the case of novell netware redirector) the previous condition will always evaluate to true, both when "x:\somewhere" is a file or when it is a folder
One alternative can be
#echo off
setlocal enableextensions
set "target=c:\windows"
set "what=NOT EXIST"
for %%a in ("%target%") do for /f "delims=r-" %%b in ("%%~aa%%~za"
) do if "%%b"=="d" ( set "what=FOLDER" ) else ( set "what=FILE" )
echo %what%
endlocal
Check for the presence of an initial d in the list of attributes of the file/folder.
Each of the attributes in the list can be a letter (depending on the attribute) or a dash.
The two first are d for directory and r for readonly. So, second for uses r- as delimiters to separate the possible d from the rest of attributes.
If the file does not have any attributes set, the tokenizer in for command will eliminate all the dashes, non assigning data to the replaceable parameter and in consecuence not executing the code inside the do clause. To avoid it, %%~za (the size of the element) is appended to the string, so, there will always be data to be processed if the file/folder exists. If it does not exist, the expresion %%~aa%%~za is evaluated to a empty string and the code in the do clause will not execute.

Find multiple values in different lines using command-line | CMD

I have multiple results (Radiology, Labs, Pathology, Transcriptions) for the same patient in a file and I am only interested in getting results for a set of particular values. For example: I want to look for a radiology report on the first line and patient MRN 123456789 on the second line.
Can this be achieved using findstr? Thanks

I used a file named q29931949.txt containing your data for my testing.
You don't really supply enough information to produce a result. For instance, is "MRN" a required data item?
This procedure will find two consecutive lines, the first one having "MSH" in he first column and "RADIOLOGY" in the second or third and the second line having "PID" in the first column snd either the second, third or fourth column containing the target number.
You'd run the routine using thisbatchaname 123456789
It accepts the parameter 123456789 and assigns that to mrn.
It then reads the file and assigns each line in tun to %%o, and tokenises the line on |, applying tokens 1-4 to %%a..%%d rspectively.
The main loop sets found to empty and then to Y only if the first field is MSH and the second or thid RADIOLOGY. If the found flag is set, the original line in %%o is applied to $1. Only if found is set at the start of the loop (which means that the previous line is MSH/RADIOLOGY) will the routine :report be called after $2 has the original contents of the second line assigned.
The :report routine sets field to the first parameter to see whether there are remaining parameters to process. The for then assigns the part of the field up to the first caret (^) to field. If this matches the mrn input from the command line, then the $ variables are echoed to the console (you don't say what you actually want to do with the data). Regardless, the remaining parameters are checked.
The reson for checking the second/third(/fourth) parameter is to cater for the presence or absence of data in the fields as consecutive | characters are interpreted as a single delimiter.

CMD - If exists <file>

The below commands (with debug lines added - indented) should only redirect the echo's output to a file, should it already exist, according to my understanding.
However, it would seem that if exist %test0% always fills the file (creating it if non-existant) with the echo's output.
Does anyone know what is wrong?
#echo off
type test.bat
set test0="e:\documents and settings\administrator\desktop\test.log"
echo.&echo.
if exist %test0% (echo !!Exists!!) else (echo !!Doesn't Exist!!)
(if exist %test0% echo.&echo.&echo -------------------------------------------------&echo.&echo.)>>%test0%
And the file gets created(!)
EDIT: This above was a simplified example, and unfortunately MSalters answer doesn't help me solve the full command (I had hoped it would). The full one line if statement is:
if exist %test0% (echo.&echo.&echo -------------------------------------------------&echo.&echo.) else (set /p .=<nul)>>%test0%&set errorlevel=0||set errorlevel=1
How would I have whichever condition of the if matched output to the file (Hopefully with only one reference to the file, i.e., not one in each if conditional), and have the errorlevel set based on the existance of the file?
Could anyone help with the actual full command issue?
You should never set ERRORLEVEL directly. That name is reserved for reporting on the results of the prior command. When you set the value directly, you override the intended functionality and it ceases to expand to the actual ERRORLEVEL, it expands to the value you set instead. That can break all kinds of code.
You can force the ERRORLEVEL to a value by running a command with known result, redirecting output to nul if necessary: ver >nul sets ERRORLEVEL to 0, set /p .=<nul sets ERRORLEVEL to 1.
You can force the ERRORLEVEL to any particular value of your choosing by using cmd /c exit /b N, where N is an integral value.
You also have faulty logic. Your IF command succeeds (has no error) regardless whether the condition evaluates to TRUE or FALSE. If you want to set the ERRORLEVEL, then you need to do it within your parenthesized blocks.
There is nothing wrong with putting everything on one line, but I find the code easier to read when using multiple lines for complex statements like yours. I believe the following is what you are looking for.
if exist %test0% (
echo.
echo.
echo -------------------------------------------------
echo.
echo.
ver >nul
) >>%test0% else (
set /p .=<nul
)
Edit in response to comments
Not much change needed.
if exist %test0% (
(
echo.
echo.
echo -------------------------------------------------
echo.
echo.
set ERR=0
) >>%test0%
) else (
copy nul %test0%
set ERR=1
)
Check your parentheses. (x) >> output.log redirects the output of x to output.log. That means the redirection happens regardless of what the output is, and in particular always creates the file.
Now if you'd write if Y (echo Text >> output.log) the redirection would be conditional on Y, and might not happen.
[edit]
With the question as it's worded now, the simple solution seems to be:
Set %ERRORLEVEL% based on exist %test0%. No redirection has happened at this point.
Use %ERRORLEVEL% to determine what to do. You can change %test0% without altering %ERRORLEVEL%.
BTW, ERRORLEVEL is not %ERRORLEVEL%

batch file to encrypt multiple archives

I have a collection of ZIP archives residing in a collection of folders inside Folder1\, with more than one zip file per folder.
I want to create a duplicate of this folder structure in another destination folder Destination\, but with all the ZIP files encrypted.
the folders inside Folder1\ are never nested any deeper than one, but a general solution that recurses into folders would be nice.
I have messed around with substrings but cannot get it to work. I'm sure I'm only a % away but it's got me stumped:
for /D %%S in (.\*) do (
echo %%S
set PN=%%S:~2,99%
echo %PN%
for %%F in (%%S\*.zip) do (
echo "%UserProfile%\Desktop\Destination\%PN%\%%~nxF"
)
)
the %%S returns a path in the form ".\Folder" and "set PN=%%S:~2,99%" is supposed to remove the ".\" but it ain't happening.
echo $$S displays ".\Folder" (without the quotes) which is OK
echo %PN% displays ".\Folder:~2,99" which is not OK
I'm OK with the unzipping/zipping, it's just the pathnames that have me stumped.
There are some issues with your script.
You cannot use substring expressions with a loop variable. You'll have to store its value to an environment variable (like SET name=%%S) and extract the substring from that variable.
Without enabling delayed expansion of variables you won't be able to use environment variables inside a command block enclosed in parentheses, if the vars are initialised within that same block. The problem is, the commands within the block are parsed (and vars are evaluated) at the same time the parent command is parsed (FOR in this case). So most probably you'll always have an empty string in place of %PN% there.
Actually you don't need the PN var. Seems like you've only introduced it to drop the .\ part of the folder name. But you don't have to use the .\* mask in the outer FOR loop, just use * instead. (Still, if .\* seems to you more meaningful, you can simply use %%~nxS where you need to substitute the folder's name.)
So, this should give you the expected output:
for /D %%S in (*) do (
for %%F in ("%%S\*.zip") do (
echo "%UserProfile%\Desktop\Destination\%%S\%%~nxF"
)
)
And if you insist on using the .\* mask:
for /D %%S in (.\*) do (
for %%F in ("%%~nxS\*.zip") do (
echo "%UserProfile%\Desktop\Destination\%%~nxS\%%~nxF"
)
)

Batch File to Determine Modified Dates

Hey guys, I'm looking for a batch file to tell me if certain folders have been modified today (I'll run it every morning). I'm happy to specify each of the folders to be to be queried, I just haven't been able to find anything that meets my requirements yet. If anyone knows off the top of their head what the code for the .bat would be, that would be awesome :) Thanks in advance.
Here's a batch file that should do the trick:
#echo off
setlocal ENABLEEXTENSIONS ENABLEDELAYEDEXPANSION
for /D %%Q IN (*.*) DO (
set FILETIME=%%~tQ
if "!FILETIME:~0,10!"=="%DATE:~4%" echo %%Q
)
This works by comparing the date-part of the file timestamp against the current date.
As written, it checks directories in the current directory, but you could replace *.* with whatever filespec you want to test (or pass it in as an argument).
I don't know if this will work on systems with anything other default English/US regional settings, but it could probably be tweaked to make it work, if it doesn't already. I also don't know what would happen if the system is shared between users in different time-zones.
you can use a vbscript
Set objFS = CreateObject( "Scripting.FileSystemObject" )
strFolder = WScript.Arguments(0)
Set objFolder = objFS.GetFolder(strFolder)
If DateDiff("d", Now, objFolder.DateLastModified ) = 0 Then
WScript.Echo "0"
End If
in your batch file (or command line)
C:\test>cscript //nologo test.vbs myFolderName
use a for loop to catch the output. (Or you can even do everything in vbscript )

How to loop through files matching wildcard in batch file

I have a set of base filenames, for each name 'f' there are exactly two files, 'f.in' and 'f.out'. I want to write a batch file (in Windows XP) which goes through all the filenames, for each one it should:
Display the base name 'f'
Perform an action on 'f.in'
Perform another action on 'f.out'
I don't have any way to list the set of base filenames, other than to search for *.in (or *.out) for example.
Assuming you have two programs that process the two files, process_in.exe and process_out.exe:
for %%f in (*.in) do (
echo %%~nf
process_in "%%~nf.in"
process_out "%%~nf.out"
)
%%~nf is a substitution modifier, that expands %f to a file name only.
See other modifiers in https://technet.microsoft.com/en-us/library/bb490909.aspx (midway down the page) or just in the next answer.
You can use this line to print the contents of your desktop:
FOR %%I in (C:\windows\desktop\*.*) DO echo %%I
Once you have the %%I variable it's easy to perform a command on it (just replace the word echo with your program)
In addition, substitution of FOR variable references has been enhanced
You can now use the following optional syntax:
%~I - expands %I removing any surrounding quotes (")
%~fI - expands %I to a fully qualified path name
%~dI - expands %I to a drive letter only
%~pI - expands %I to a path only (directory with \)
%~nI - expands %I to a file name only
%~xI - expands %I to a file extension only
%~sI - expanded path contains short names only
%~aI - expands %I to file attributes of file
%~tI - expands %I to date/time of file
%~zI - expands %I to size of file
%~$PATH:I - searches the directories listed in the PATH
environment variable and expands %I to the
fully qualified name of the first one found.
If the environment variable name is not
defined or the file is not found by the
search, then this modifier expands to the
empty string
https://ss64.com/nt/syntax-args.html
In the above examples %I and PATH can be replaced by other valid
values. The %~ syntax is terminated by a valid FOR variable name.
Picking upper case variable names like %I makes it more readable and
avoids confusion with the modifiers, which are not case sensitive.
You can get the full documentation by typing FOR /?
Easiest way, as I see it, is to use a for loop that calls a second batch file for processing, passing that second file the base name.
According to the for /? help, basename can be extracted using the nifty ~n option. So, the base script would read:
for %%f in (*.in) do call process.cmd %%~nf
Then, in process.cmd, assume that %0 contains the base name and act accordingly. For example:
echo The file is %0
copy %0.in %0.out
ren %0.out monkeys_are_cool.txt
There might be a better way to do this in one script, but I've always been a bit hazy on how to pull of multiple commands in a single for loop in a batch file.
EDIT: That's fantastic! I had somehow missed the page in the docs that showed that you could do multi-line blocks in a FOR loop. I am going to go have to go back and rewrite some batch files now...
Expanding on Nathans post. The following will do the job lot in one batch file.
#echo off
if %1.==Sub. goto %2
for %%f in (*.in) do call %0 Sub action %%~nf
goto end
:action
echo The file is %3
copy %3.in %3.out
ren %3.out monkeys_are_cool.txt
:end
There is a tool usually used in MS Servers (as far as I can remember) called forfiles:
The link above contains help as well as a link to the microsoft download page.
The code below filters filenames starting with given substring. It could be changed to fit different needs by working on subfname substring extraction and IF statement:
echo off
rem filter all files not starting with the prefix 'dat'
setlocal enabledelayedexpansion
FOR /R your-folder-fullpath %%F IN (*.*) DO (
set fname=%%~nF
set subfname=!fname:~0,3!
IF NOT "!subfname!" == "dat" echo "%%F"
)
pause
Echoing f.in and f.out will seperate the concept of what to loop and what not to loop when used in a for /f loop.
::Get the files seperated
echo f.in>files_to_pass_through.txt
echo f.out>>files_to_pass_through.txt
for /F %%a in (files_to_pass_through.txt) do (
for /R %%b in (*.*) do (
if "%%a" NEQ "%%b" (
echo %%b>>dont_pass_through_these.txt
)
)
)
::I'm assuming the base name is the whole string "f".
::If I'm right then all the files begin with "f".
::So all you have to do is display "f". right?
::But that would be too easy.
::Let's do this the right way.
for /f %%C in (dont_pass_through_these.txt)
::displays the filename and not the extention
echo %~nC
)
Although you didn't ask, a good way to pass commands into f.in and f.out would be to...
for /F %%D "tokens=*" in (dont_pass_through_these.txt) do (
for /F %%E in (%%D) do (
start /wait %%E
)
)
