The following code runs at the CMD line, but get error "Expected end of statement", Line: 1 Char 11.
sqlcmd -S DONALDLT-PC\SQLEXPRESS -E -i C:\SQL\append_ToTblPurchaseDetials.sql
Its failing because your syntax is incorrect. You can not execute shell scripts directly in visual basic. The statements/parameters need to be properly escaped and passed to some type of execute method. If you are already doing this, please add the entire code.

What's the Windows batch file equivalent of set -o errexit in a bash script?
I have a long batch file filled with different programs to run on Windows command line... basically its an unrolled make file with every compiler command that needs to be run to build an exe in a long sequence of commands.
The problem with this method is that I want it to exit the batch command on the first non-zero return code generate by a command in the script.
As far as I know, Windows batch files have a problem where they don't automatically exit on the first error without adding a lot of repetitive boilerplate code between each command to check for a non-zero return code and to exit the script.
What I'm wondering about, is there an option similar to bash's set -o errexit for Windows cmd.exe? or perhaps a technique that works to eliminate too much boilerplate error checking code... like you set it up once and then it automatically exits if a command returns a non-zero return code without adding a bunch of junk to your script to do this for you.
(I would accept PowerShell option as well instead of cmd.exe, except PowerShell isn't very nice with old-unix-style command flags like: -dontbreak -y ... breaking those commands without adding junk to your command line like quotes or escape characters... not really something I want to mess around with either...)
CMD/Batch
As Ken mentioned in the comments, CMD does not have an equivalent to the bash option -e (or the equivalent -o errexit). You'd have to check the exit status of each command, which is stored in the variable %errorlevel% (equivalent to $? in bash). Something like
if %errorlevel% neq 0 then exit /b %errorlevel%
PowerShell
PowerShell already automatically terminates script execution on errors in most cases. However, there are two error classes in PowerShell: terminating and non-terminating. The latter just displays an error without terminating script execution. The behavior can be controlled via the variable $ErrorActionPreference:
$ErrorActionPreference = 'Stop': terminate on all errors (terminating and non-terminating)
$ErrorActionPreference = 'Continue' (default): terminate on terminating errors, continue on non-terminating errors
$ErrorActionPreference = 'SilentlyContinue': don't terminate on any error
PowerShell also allows more fine-grained error handling via try/catch statements:
try {
# run command here
} catch [System.SomeException] {
# handle exception of a specific type
} catch [System.OtherException] {
# handle exception of a different type
} catch {
# handle all other exceptions
} finally {
# cleanup statements that are run regardless of whether or not
# an exception was thrown
}
I am having trouble launching an executable that I have created from a shell script. I would like to automate testing by running the program many times with different command line options to verify it is working.
When I type echo $SHELL, /bin/sh is displayed.
The following is my shell script:
#!/bin/sh
clear
echo "Running first test."
./myProgram
exit 0
When I run the script (sh myScript.sh), with myProgram in the same directory, I see the following output:
Running first test.
: not foundsh: line 4:
When executing the program ./myProgram, it runs as expected with no command line options.
I have also tried:
myProgram
./myProgram &
myProgram &
based on answers to somewhat similar questions, but they all result in the above error message.
Your newlines are goofed. Use dos2unix to fix.
why don't you try using the full path?
e.g., if myProgram is in /home/user1/bin, you can try /home/user1/bin/myProgram instead of ./myProgram. This should work.
You can also add the path to path variable, $PATH and directly call myProgram from anywhere.
Run "export PATH=$PATH:/home/user1/bin" on your terminal without the quotes. Note that this affects only your current termial session. If you want to permanently add the path, update your .bashrc file in your home directory with the following line:
I am using mr on Windows and it allows running arbitrary commands before/after any repository action. As far as I can see this is done simply by invoking perl's system function. However something seems very wrong with my setup: when making mr run the following batch file, located in d:
#echo off
copy /Y foo.bat bar.bat
I get errors on the most basic windows commands:
d:/foo.bat: line 1: #echo: command not found
d:/foo.bat: line 2: copy: command not found
To make sure mr isn't the problem, I ran perl -e 'system( "d:/foo.bat" )' but the output is the same.
Using xcopy instead of copy, it seems the xcopy command is found since the output is now
d:/foo.bat: line 1: #echo: command not found
Invalid number of parameters
However I have no idea what could be wrong with the parameters. I figured maybe the problem is the batch file hasn't full access to the standard command environment so I tried running it explicitly via perl -e 'system( "cmd /c d:\foo.bat" )' but that just starts cmd and does not run the command (I have to exit the command line to get back to the one where I was).
What is wrong here? A detailed explanation would be great. Also, how do I solve this? I prefer a solution that leaves the batch file as is.
The echo directive is executed directly by the running command-prompt instance.
But perl is launching a new process with your command. You need to run your script within a cmd instance, for those commands to work.
Your cmd /c must work. Check if you have spaces in the path you are supplying to it.
You can use a parametrized way of passing arguments,
#array = qw("/c", "path/to/xyz.bat");
system("cmd.exe", #array);
The echo directive is not an executable and hence, it errors out.
The same is true of the copy command also. It is not an executable, while xcopy.exe is.
This question is regarding dollar signs "$" $ in Windows PowerShell ISE.
I have PHP CLI and want to run one liner command scripts from the prompt in Windows PowerShell ISE.
php -r "$foo = 'foo';"
Just returns Parse error: parse error in Command line code on line 1 and I've narrowed it down to the pesky dollar sign which is significant in PowerShell. Can I escape it somehow?
I also tried
php -r '$foo = "foo";'
and get
Notice: Use of undefined constant foo - assumed 'foo' in Command line code on line 1
Yes, add a backtick in front of the dollar sign:
php -r "`$foo = 'foo';"
This is what you need:
"`$foo = 'foo';"
Is it newline? prompt? What exactly?
Trying to run powershell over plink and the command executes but plink doesn't recognise its finished and the session hangs. Most curiously though, the command executes successfully when sent through the shell (via Putty). However, when sent via plink, the same command hangs...
Any ideas?
Telnet is nearly a raw TCP connection. All Putty needs back is a response from the server. The rest is controlled by the shell and SSH/Telnet server.
While your task is running, it's not going to return a command prompt.
On Linux, Unix, and Mac OS X you could put a & after the command to run it in the background and return to the command prompt.
Try running it in the local terminal/command shell. You should basically see the same thing.
Ok, well I'm still not quite sure what the problem is, but I've found a workaround via the TeamCity forums.
Basically you want to echo some abitrary string and pipe that output into your powershell executable, like thus:
echo 'executing powershell...' | C:\windows\system32\windowspowershell \v1.0\powershell.exe exit 1
So then your full plink command becomes:
plink.exe user#someIp -i key.ppk -P 22 -batch -v "echo 'executing powershell...' | C:\windows\system32\windowspowershell\v1.0\powershell.exe exit 1"
Nb. Plink will still pass through return codes and console output using this method.

Hope this helps
I had the same problem with an other program. I used the >&2 (redirect output to std err) after the last command, this worked fine for me.
Just add "return XX" into remote shell script, it will be return value to local console. After plink has been finished, type echo %errorlevel% to see return code XX.
