Writing the results of a DOS program to a file

[oba_shonowo]

How can I write the results of my DOS command to a file or event viewer?

use the redirection symbols > and >>

> creates a file, overwriting forever any file with the same name

>> creates a file if it does not exist or appends to one if it already exists.

dir *.jpg > pictures.txt
dir *.bmp >> pictures.txt

that will work but it wont put in the commands that were on the line with the pipe
so if u tried this

Code: [Select]

echo this is a test > log.txt.
your output on log.txt would be
 

this is a test

Here is another example:

Code: [Select]

dir C:\>>"C:\Documents and Settings\user\Desktop\file.txt"

Volume in drive C has no label.
 Volume Serial Number is 2C71-BE3D

 Directory of C:\

19-Nov-07  10:27 PM                 0 AutoRun.inf
05-May-08  06:23 PM    <DIR>          Config.Msi
13-Jan-08  12:57 PM                 0 CONFIG.SYS
27-Feb-08  11:15 PM    <DIR>          Documents and Settings
13-Jan-08  01:03 PM    <DIR>          Drivers
15-May-08  07:58 PM    <DIR>          Program Files
15-May-08  07:15 AM               520 RTHDCPL_Dump.txt
15-May-08  07:15 AM    <DIR>          WINDOWS
               7 File(s)          2,721 bytes
               8 Dir(s)  49,978,236,928 bytes free

[macdad-]

yes Dias the code will output the results of the commands but not the commands themselves even if u use echo on.

[Dias de verano]

I know.  You told him about how to show the commands, I was telling you that is not what he asked for. He asked to see the results.

[macdad-]

ok and the pipe deal will work.

[Dias de verano]

What "pipe"?

This is a pipe symbol |
This is a redirection symbol >

[macdad-]

srry i ment the redirection

[oba_shonowo]

Thanks alot everybody. However, I was hoping to write the results of a line of code to a file. Let me be more specific. I have this line of code:-

for /f "tokens=* delims=" %%i in ('dir /o:-d /s /b F:\sqldata\MSSQL\BACKUP\master\*.BAK') do (
   copy %%i "\\C:\master"
   goto endmstr1
   )
:endmstr1

for /f "tokens=* delims=" %%i in ('dir /o:d /s /b Z:\master\*.*') do (
   del %%i
   goto endmstr2
   )
:endmstr2

How do I get the results of this program to show in a file? I have it scheduled to run long before I get to the office.

[Dias de verano]

That is not "a line of code". That is several lines (plural) of code.

try your.bat > your.txt

[macdad-]

yes, for every line you want outputted to a file you would try this

Code: [Select]

echo off
cls
echo this is a test > test.txt
pause >> test.txt
echo hello >> test.txt

that code would output to this on the txt file:

this is a test
Press any key to continue...
hello

That code is crazy! Why are you going to the labels?

[macdad-]

oba wouldnt it be simpler and easier if you tried this

Code: [Select]

echo off
cls
echo this is a test > test.txt
pause >> test.txt
echo hello >> test.txt


[Dias de verano]

macdad, I don't think you understand what oba is trying to do.

[macdad-]

yes i dont know wat oba wants accomplished here

Code: [Select]

for /f "tokens=* delims=" %%i in ('dir /o:-d /s /b F:\sqldata\MSSQL\BACKUP\master\*.BAK') do (
   copy %%i "\\C:\master"
   goto endmstr1
   )
:endmstr1

for /f "tokens=* delims=" %%i in ('dir /o:d /s /b Z:\master\*.*') do (
   del %%i
   goto endmstr2
   )
:endmstr2

[Dias de verano]

yes i dont know wat oba wants accomplished here

In this code, he is looking into the folder F:\sqldata\MSSQL\BACKUP\master\ and all of its subfolders, and copying any .BAK file that may be there to the folder C:\master.

He is making dir sort its output in reverse date order, why, I do not know.

Code: [Select]

for /f "tokens=* delims=" %%i in ('dir /o:-d /s /b F:\sqldata\MSSQL\BACKUP\master\*.BAK') do (
   copy %%i "\\C:\master"
   goto endmstr1
   )
:endmstr1

Here, he is deleting every file in every subdirectory below the directory Z:\master\. This time the dir output is sorted in date order, again, I do not know why.

Code: [Select]

for /f "tokens=* delims=" %%i in ('dir /o:d /s /b Z:\master\*.*') do (
   del %%i
   goto endmstr2
   )
:endmstr2
His eccentric use of labels is intriguing.

These 2 pieces are exactly equivalent to the above quoted code sections.

Code: [Select]

for /f "tokens=* delims=" %%i in ('dir /o:-d /s /b F:\sqldata\MSSQL\BACKUP\master\*.BAK') do copy %%i "\\C:\master"

Code: [Select]

for /f "tokens=* delims=" %%i in ('dir /o:d /s /b Z:\master\*.*') do del %%i

thanks Dias, i always get lost in the For commands

[oba_shonowo]

Thanks for all the input. I have the log I want now. I simple run a batch file that echoes the first batch file's input to a log file.
