I'm using scpg3 command to copy file from local server to a remote server. My command is as below:
scpg3 <filename> user#remotehost:/tmp
My question is: how to get the result from this command. I want to move it to backup folder after copy successfully. Thanks
There is a verbose directly. You can use that:
scpg3 -v, --verbose
in your case,
scpg3 -v <filename> user#remotehost:/tmp
Uses verbose mode which is equal to -D 2. -D only applies on Unix. On Windows, instead of this command line tool, use the Connection Broker debugging options -D, -l.
D is the Debug level.
Hope it helps.

I have the need to start a java rest server with concourse that lives on an Ubuntu 18.04 machine. The version of concourse my company uses is 5.5.11. The server code is written in Java, so a simple java -jar <uber.jar> suffices from the command line (see below). In production, I will not have this simple luxury, hence my question.
I have an scp command working that copies the .jar from concourse to the target Ubuntu machine:
scp -i /tmp/key.p8 -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null ./${NEW_DIR}/${ARTIFACT_NAME}.${ARTIFACT_FILE_TYPE} ${SRV_ACCOUNT_USER}#${JAVA_VM_HOST}:/var/www
Note that my private key is passed with -i and I can confirm that is working.
I followed this other SO Q&A that seemed to be promising: Getting ssh to execute a command in the background on target machine
, but after trying a few permutations of the suggested solution and other answers, I still don't have my rest service kicked off.
I've tried a few permutations of this line in my concourse script:
ssh -f -i /tmp/pvt_key1.p8 -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null ${SRV_ACCOUNT_USER}#${JAVA_VM_HOST} "bash -c 'nohup java -jar /var/www/${ARTIFACT_NAME}.${ARTIFACT_FILE_TYPE} -c \"/opt/testcerts/clientkeystore\" -w \"password\" > /dev/null 2>&1 &'"
I've tried with and without the -f and -t switches in ssh, with and without the file stream redirection, with and without nohup and the Linux background ('&') command and various ways to escape the quotes.
At the bash prompt, this line successfully starts my server. The two switches are needed to point to the certificate and provide the password:
java -jar rest-service.jar -c "/opt/certificates/clientkeystore" -w "password"
I really think this is possible to do in Concourse, but I'm stuck at this point.
After a lot of trial an error, it seems I needed to do this:
ssh -f -i /tmp/pvt_key1.p8 -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null ${SRV_ACCOUNT_USER}#${JAVA_VM_HOST} "bash -c 'sudo java -jar /var/www/${ARTIFACT_NAME}.${ARTIFACT_FILE_TYPE} -c \"/path/to/my/certificate\" -w \"password\" > /var/www/log.txt 2>&1 &'"
The key was I was missing the 'sudo' portion of the command. Using nohup as opposed to putting in a Linux bash background indicator ('&') seems to give me an error in the pipeline. This works for me, but others are welcome to post responses with better answers or methods that might be a better practice.
On RHEL, the below command works:
psql -h hostname -U username -p port_no -d database -f /tmp/myfile.sql &> logfile01.txt
On FreeBSD, this throws error:
"Invalid null command"
Please suggest.
If you use this only on the command line then there is no need to change the shell.
To redirect stdout and stderr to a file in C-Shell synthax simply use ">& filename".
Different story is, if you want to write shell scripts. Bourne Shell and it's clones (like i.e. Bash) are better suited for writing script. See this Unix FAQ "Csh Programming Considered Harmful": http://www.faqs.org/faqs/unix-faq/shell/csh-whynot/
This redirection works in bash
&> logfile01.txt
, but it does not work in csh which is the default shell in FreeBSD.
# set | grep shell
shell /bin/csh
# ls -la &> logfile01.txt
Invalid null command.
Bash is not installed by default. You can install it
pkg install bash
and configure it as the default shell.
What's the proper way to log any errors or warnings when performing a quiet rsync?
This is what I currently run from my crontab:
gsutil -m -q rsync -r -C /mount1/share/folder gs://my-bucket-1/folder/ > /mount2/share/folder/gsutil.log
Since the log file is always completely empty and I'm uploading terabytes of data I'm starting to think that maybe even errors and warnings are being supressed.
After having realized that this is related to how you pipe stdout and/or stderr to files in general, the answer really lies within this existing thread: How to redirect both stdout and stderr to a file
So a simple solution to log as much as possible into one single log file could be something like:
gsutil -d rsync [src] [dst] &> [logfile]
...where -d enables debug output. I found this to be the only way to show files which were affected by an error such as CommandException: 3 files/objects could not be copied. Please note that -d exposes authentication credentials.
I am new to jmeter. I have the .jmx file containg all the required http samplers. I could run it throught the Jmeter UI using "Run-> Start" and view the result in the "Summary Report". I can then save the results to the .csv using "Save Table Data" button in "Summary Report".
Question is how can I achieve the same using command line.
JMeter can be launched in non-GUI mode as follows:
jmeter -n -t /path/to/your/test.jmx -l /path/to/results/file.jtl
You can set what would you like to see in result jtl file via playing with JMeter Properties.
See jmeter.properties file under /bin folder of your JMeter installation and look for those starting with
jmeter.save.saveservice.
Defaults are listed below:
#jmeter.save.saveservice.output_format=csv
#jmeter.save.saveservice.assertion_results_failure_message=false
#jmeter.save.saveservice.assertion_results=none
#jmeter.save.saveservice.data_type=true
#jmeter.save.saveservice.label=true
#jmeter.save.saveservice.response_code=true
#jmeter.save.saveservice.response_data=false
#jmeter.save.saveservice.response_data.on_error=false
#jmeter.save.saveservice.response_message=true
#jmeter.save.saveservice.successful=true
#jmeter.save.saveservice.thread_name=true
#jmeter.save.saveservice.time=true
#jmeter.save.saveservice.subresults=true
#jmeter.save.saveservice.assertions=true
#jmeter.save.saveservice.latency=true
#jmeter.save.saveservice.samplerData=false
#jmeter.save.saveservice.responseHeaders=false
#jmeter.save.saveservice.requestHeaders=false
#jmeter.save.saveservice.encoding=false
#jmeter.save.saveservice.bytes=true
#jmeter.save.saveservice.url=false
#jmeter.save.saveservice.filename=false
#jmeter.save.saveservice.hostname=false
#jmeter.save.saveservice.thread_counts=false
#jmeter.save.saveservice.sample_count=false
#jmeter.save.saveservice.idle_time=false
#jmeter.save.saveservice.timestamp_format=ms
#jmeter.save.saveservice.timestamp_format=yyyy/MM/dd HH:mm:ss.SSS
#jmeter.save.saveservice.default_delimiter=,
#jmeter.save.saveservice.default_delimiter=\t
#jmeter.save.saveservice.print_field_names=false
#jmeter.save.saveservice.xml_pi=<?xml-stylesheet type="text/xsl" href="../extras/jmeter-results-detail-report_21.xsl"?>
#jmeter.save.saveservice.base_prefix=~/
#jmeter.save.saveservice.autoflush=false
Uncomment the one you are interested in and set it's value to change the default. Another option is override property in user.properties file or provide it as a command-line argument using -J key as follows:
jmeter -Jjmeter.save.saveservice.print_field_names=true -n /path/to/your/test.jmx -l /path/to/results/file.jtl
See Apache JMeter Properties Customization Guide for more details on what can be done using JMeter Properties.
You can use this command,
jmeter -n -t /path to the script.jmx -l /path to save results with file name file.jtl
But if you really want to run a load test in a remote machine, you should be able to make it run eventhough you close the window. So we can use nohup to ignore the HUP (hangup) signal. So you can use this command as below.
nohup sh jmeter.sh -n -t /path to the script.jmx -l /path to save results with file name file.jtl &
You can run JMeter from the command line using the -n parameter for 'Non-GUI' and the -t parameter for the test plan file.
jmeter -n -t "PATHTOJMXFILE"
If you want to further customize the command line experience, I would direct you to the 'Getting Started' section of their documentation.
This worked for me on mac os High sierra 10.13.6, java 8 64-bit, jmeter 4.0
$ jmeter -n --testfile /path/to/Test_Plan.jmx
Sample output:
Creating summariser <summary>
Created the tree successfully using ./src/test/jmeter/Test_Plan.jmx
Starting the test # Fri Aug 24 17:18:18 PDT 2018 (1535156298333)

... end of run
To get the results in excel like file, you have one option to get it done with csv file.
Use below commands with provided options.
jmeter -n -t /path-to-jmeter-test/file.jmx -l TestResults.csv
-n states Non GUI mode
-t states Test JMX File
-l state Log the results in provided file
Also you can pass any results related parameters dynamically in command line arguments using -Jprop.name=value which are already defined in jmeter.properties in bin folder.
This would be the command line statement.
"%JMETER_HOME%\bin\jmeter.bat" -n -t <jmx test file path> -l <csv result file path> -Djmeter.save.saveservice.output_format=csv
In Command line mode:
I have planned on Linux OS.
download the latest jmeter version. Apache JMeter 3.2 (Requires Java 8 or later) as of now.
Extract in your desired directory. For example, extract to /tmp/
Now, default output file format will be csv. No need to change anything or specify in the CLI command.
for example:
./jmeter -n -t examples/test.jmx -l examples/output.csv
For changing the default format, change the following parameter in jmeter.properties : jmeter.save.saveservice.output_format=xml
Now if you run the command : ./jmeter -n -t examples/test.jmx -l examples/output.jtl
output get stored in xml format.
Now, make the request on multiple server(Additional info query): We can specify
host and port as tags in
./jmeter -n -t examples/test.jmx -l examples/output.jtl -JHOST=<HOST> -JPORT=<PORT>
Check my powershell command
$Date = Get-Date -Format ddMMyyyyhhmmss
jmeter -n -t jmetter\dev.jmx -l jmetter\TestResult-$Date.csv -o jmetter\Results-$Date\ -X
// For to know all parameter (like -n, -t, ...), use this command:
jmeter --?
Running JMeter in command line mode:
1.Navigate to JMeter’s bin directory
Now enter following command,
jmeter -n –t test.jmx
-n: specifies JMeter is to run in non-gui mode
-t: specifies name of JMX file that contains the Test Plan
For a while i have my db running on a command window because im not figuring out how to run it as a windows service.
Since i have the zip file version downloaded. how can i register the pg_ctl command as a windows service?
By the way, im using the following line to start the server:
"D:/Program Files/PostgreSQL/9.0.4/bin/pg_ctl.exe" -D "D:/Program Files/PostgreSQL/9.0.4/db_data" -l logfile start
Thanks in advance.
Use the register parameter for the pg_ctl program.
The data directory should not be stored in Program Files, the location of %ProgramData% is e.g. a good choice.
pg_ctl.exe register -N PostgreSQL -U some_windows_username -P windows_password -D "%ProgramData%/db_data" ...
In newer versions of Postgres, a separate Windows account is no longer necessary, so the following is also sufficient
pg_ctl.exe register -N PostgreSQL -D "%ProgramData%/db_data" ...
Details are in the manual: http://www.postgresql.org/docs/current/static/app-pg-ctl.html
You need to make sure the directory D:/Program Files/PostgreSQL/9.0.4/db_data has the correct privileges for the windows user you specify with the -U flag.
Btw: it is a bad idea to store program data in Program Files. You should move the data directory somewhere outside of Program Files because Program Files is usually highly restricted for regular users - with a very good reason.
Just run 'Command Prompt' as windows administrator and run the below command:
pg_ctl.exe register -N PostgreSQL -D "D:/Program Files/PostgreSQL/9.0.4/db_data"
You don't need to specify a User and Password, as previous answers have suggested.
