Is there any utility in windows which carries out same operations done but cut command in unix.
I have input lets say A|B|C|D. Since "|" is the delimiter therefore I need to fetch all values separated by "|".
Kindly advise.
If you are trying to do this in a .cmd file you can probably find some examples by typing for /? into your command prompt. Otherwise if powershell is an option then it's as easy as using String.Split().

I have a text file with lots of commands in it and I want to sent those commands to a software called thermocal. It is a console application. I found the command below, but it doesn't work for me.
Do I need to put this .exe file in the same folder of the batch file to make it work or any thing else?
type somefile.txt | Thermocal.exe
Batch scripts can be considered as a collection of lines you could also type in a command line prompt one after another. With respect to this it might be helpful for you, to play with cmd in order to get a feeling for what is happening.
About starting thermocal: Assuming thermocal is not part of PATH then the batch file either needs to change the current directory to the one with termocal.exe. Alternatively you might be able to call thermocal.exe with adding a path like C:\ProgramFiles\Thermocal\thermocal.exe . Play with cmd to find out, what works and what doesn't
When you are able to start thermocal from the command line prompt window, you can start experimenting with the call. You will probably end of with something like this in your command line window:
C:\ProgramFiles\Thermocal> thermocal argument1 argument 2
If this works, you can start with batch programming :)
Assuming your arguments are stored in somefile.txt like this:
argument1 argument 2
TYPE does nothing more than printing a file:
TYPE somefile.txt
Now you need to use the result of the output as command line arguments:
for /f %%i in ('type somefile.txt') do (thermocal.exe %%i)
I am writing a simple batch script, and I need to delete one line from the file that gets downloaded by the script. What is the easiest way to do this using ONLY the command prompt? I have come across several various suggestions, but nothing to very simply delete one string that is constant across all files that are downloaded with the script.
This is a very platform dependant question. If you are using a *nix environment (Linux / Mac environment using bash / shell), you can accomplish this with sed
sed '/${regular_expression_that_matches_line_to_be_removed}/d' yourFile.txt > newFile.txt
This will generate a new file called newFile.txt that will contain the output. You can also do this in place (it modifies the file it's using as input), but I recommend against that because if you mess up your regex, you've lost your input.
If you're using a Windows environment (which I assume you are due to your batch-file tag), try looking at this Delete certain lines in a txt file via a batch file
I have a demo.txt file. I need to delete content in that file using a batch file. Please tell me the command to delete content for demo.txt file.
break>demo.txt
Try this.it will set an empty file on the place of demo.txt. As break is internal command that does nothing it should be pretty fast.Also the break command can produce output only with /? argument so this makes this method pretty robust.
Command Prompt:
break>c:\'file directory'\demo.txt
PowerShell:
Clear-Content c:\'file directory'\demo.txt
type nul > demo.txt
works and also works in JPSoft's TakeCommand TCC.EXE command shell (where "break" will output "BREAK is ON" rather than nothing as it does in Microsoft CMD.EXE)
The general idea is to find a command that outputs Nothing and redirect that to the file using >
This seems most intuitive to me:
copy /y nul demo.txt
NOTE: Unfortunately, like the other methods provided here, this fails if demo.txt is currently in use by another process. In such a case it is sometimes possible to open the file in a text editor and delete all the contents, even though the file is in use. I don't know of a way to do this from the command line.
If the file is used by another application command prompt redirection may fail (as it requires more file access then necessary). In that case you can use powershell:
PS> Set-Content file.txt $null
Note: do not expect that it will allow access to exclusively opened files.
I have a simple .bat file
#echo; set nls_lang=russian_cis.ru8pc866
#echo off
SET NLS_NUMERIC_CHARACTERS=. '
sqlldr.exe userid=PRB/0611#TSESTDB control=control_file.ctl LOG=fdb_log.log errors=100
cmd
and i need to convert to .sh file for running on the UNIX based pc.
I began to read "BASH Programming - Introduction HOW-TO" (is it suitable for beginners?), but it is a episodical task and dead line comes.
Could anybody help me to convert file? Thanks a lot!!!
rewriting your script.
#!/bin/bash
# #echo;
# set nls_lang=russian_cis.ru8pc866
export NLS_LANG=russian_cis.ru8pc866
# not needed #echo off
# SET NLS_NUMERIC_CHARACTERS=. '
export NLS_NUMERIC_CHARACTERS='.'
PATH="/path/to/sqlDir/install:${PATH}"
# sqlldr.exe userid=PRB/0611#TSESTDB control=control_file.ctl LOG=fdb_log.log errors=100
sqlldr userid=PRB/0611#TSESTDB control=control_file.ctl LOG=fdb_log.log errors=100
# ? cmd
I've left your code in, but commented out (using the shell comment char '#'). The uncommented lines are the 'translation' of .bat syntax into Linux/Unix bash/shell syntax.
There some things above that you may need to fix:
You'll have to include the correct value in the resetting of PATH,
note that the value there is strictly to illustrate the issue.
export is used so that variables set in the current shell (the
shell script) are visible to child processes that run from the shell
script, in this case the important one being sqlldr
I'm not sure what values you really need assigned to
NLS_NUMERIC_CHARACTERS. Note that by quoting with the single-quote
char ' available to the shell, you should get exactly the value
used that you intended. If '*' or other reg-exp chars are used, this
may cause problems.
You may find that sqlldr.exe has a different name altogether. The
linux/unix convention for executable commands does not require the
.exe extension, so I have used sqlldr. Just use the full name of
the program you find in the installed directory.
The line with #!/bin/bash needs to be the first line in the file, with no leading spaces.
You'll also need to inform your OS that the script is intended to be executable. From a bash cmd line, IN the directory that contains this script, do
chmod 755 mySQLLDR_runningScript
Finally, not sure why you have cmd at the end of your .bat file, to open a new window? You'll need to experiment on your system to find the correct cmd to do that. Maybe xterm.
I hope this helps.
I'm writing a .bat file to handle some script generation automatically so I don't have to type in half a dozen command arguments each time I want to run it.
I have to run a vb script from the batch file
#call ..\Database\scripts\runscriptupdates.vbs
However the script will only run if using the the command prompt from
C:\Windows\SysWOW64\cmd.exe
By default the bat file uses the cmd.exe in system32
C:\Windows\System32\cmd.exe
Is there a way to force the batch file to use this cmd.exe to run the vbs file? I've been trawling the web for about an hour now and haven't found anything which helps (so far).
I've tried running the syswow64 with "start ..." however it doesn't seem to take the arguments after it.
Many thanks, Neil
You can try:
%windir%\SysWoW64\cmd.exe /c mybatch.bat
This will run the batch itself from a 32-bit command prompt. Thus, the call to your vbs will also be coming from a 32-bit command prompt.
I also had this problem, and I found the way to solve it.
You just need to change System Variables.
Go to Control Panel » System » Advanced System Settings » Environment Variables.
Find the variable ComSpec, then just click Edit... and change the path to "C:\Windows\SysWow64\cmd.exe"
Try typing this one line in your batch file.
%windir%\SysWoW64\cmd.exe /c ["]cscript [script name] [host options] [script arguments]["]
Where:
script name is the name of the script file, including the file name extension and any necessary path information.
host options are the command-line switches that enable or disable various Windows Script Host features. Host options are always preceded by two slashes (//).
script arguments are the command-line switches that are passed to the script. Script arguments are always preceded by one slash (/).
Example:
%windir%\SysWoW64\cmd.exe /c "cscript VoltageDrop.vbs /"Campbell.sin" "L08""
Note: In this line I do not pass any host options. This command will execute the string,
cscript VoltageDrop.vbs /"Campbell.sin" "L08"
as a command in the 32-bit command prompt.
