I want to find what version of Outlook is running on specific workstations. If I manually run
wmic /node:"hostname" product where "Name like '%Office Outlook%'" get Name
in a command line, it works. But if I run it from a batch file, it returns "No instance(s) available". I've even stripped everything else out of the batch file, so only this line is left - and I still get the same result. Am I missing something?
In a batch script file, escape your %s by prefacing each with another % as follows:
wmic /node:"hostname" product where "Name like '%%Office Outlook%%'" get Name
For proof, try next in your batch file:
echo ON
wmic /node:"hostname" product where "Name like '%%Office Outlook%%'" get Name
pause
You should see next ECHOed command, the same as it would be typed from command prompt:
wmic /node:"hostname" product where "Name like '%Office Outlook%'" get Name

Escaping Percents
The % character has a special meaning for command line parameters and
FOR parameters. To treat a percent in a batch script file as a
regular character, double it: %%

I am creating a test case in Robot framework that checks the memory usage of an application and does some further actions. I am running a keyword that executes a command on command line and returns the output.
I am using that keyword to run the command wmic process where name=\"${executableName}\" get WorkingSetSize
If we run this command on command prompt we get an output like
WorkingSetSize
353242342
I am executing this command in robot framework using a keyword but I want to modify the output such that I can just store the number in the variable without the "WorkingSetSize" or newline found in my output. How should I approach this?
If the string contains space in between string and Number, then try this
${String and number} hello 123
${number only} Evaluate "${String and number}".split(" ")[1]
Same way you can use any separator in the split function.
I am trying to pull all the jdk packages installed on set of hosts by sending a sql select statement to osquery on linux shell via pssh .
Here is the query:
pssh -h myhosts -i 'echo "SELECT name FROM rpm_packages where name like '%jdk%';"| osqueryi --json'
but usage of "%" is giving me below error.
Error: near line 1: near "%": syntax error
I tried to escape % ,but the error remains same. Any ideas how to overcome this error?
You aren't getting this error from your shell but from the query parser, and it's not actually caused by the % character, but to the ' that immediately precedes it. Look at where you have quotes:
'echo "SELECT name FROM rpm_packages where name like '%jdk%';"| osqueryi --json'
^----------------------------------------------------^ ^-------------------^
These quotes are consumed by the shell when it parses the argument. Single quotes tell the shell to ignore any otherwise-special characters inside and treat what is within the quotes as part of the argument -- but not the quotes themselves.
After shell parsing finishes, the actual, verbatim argument that gets sent to pssh looks like this:
echo "SELECT name FROM rpm_packages where name like %jdk%;"| osqueryi --json
Note that all of the single quotes have been erased. The result is that your query tool sees the % (presumably modulus) operator in a place that it doesn't expect -- right after another operator (like) which makes about as much sense to the parser as name like * jdk. The parser doesn't understand what it means to have two consecutive binary operators, so it complains about the second one: %.
In order to get a literal ' there, you need to jump through this hoop:
'\''
^^^^- start quoting again
|||
|\+-- literal '
|
\---- stop quoting
So, to fix this, replace all ' instances inside the string with '\'':
pssh -h myhosts -i 'echo "SELECT name FROM rpm_packages where name like '\''%jdk%'\'';"| osqueryi --json'
osqueryi accepts a single statement on the command line. Eliminating the echo can make quoting a bit simpler:
osqueryi --json "SELECT * FROM users where username like '%jdk%'"
You will, however, need the quotes to pass through your pssh command line.
While osqueryi is great for short simple things, if you're building a frequent polling service, osqueryd with scheduled queries is generally simpler.
I created a batch script for windows that I use for mux mkv files.
When launch this command:
ffprobe -v 0 -select_streams s -show_entries stream=index:disposition=default -of compact=nk=0 file.mkv | findstr disposition:default=1
Output is:
stream|index=3|disposition:default=1
How can filter and print only number "3" and put it in a variable?
I submit a new command that simplify output:
ffprobe -v 0 -select_streams s -show_entries stream=index:disposition=forced:stream_tags=language -of csv=nk=1:p=0 file.mkv | FINDSTR /C:"1,ita"
Output is:
3,1,ita
"3" is track id, "1" is forced flag, "ita" is track language. To create a variable that contains only the track id (e.g. 3) to be inserted in a mkvmerge command, I ran this command:
FOR /F "delims=, tokens=1" %%# IN ('ffprobe -v 0 -select_streams s -show_entries stream=index:disposition=forced:stream_tags=language -of csv=nk=1:p=0 file.mkv ^| FINDSTR /C:"1,ita"') DO SET subid=%%#
But nothing happens! Mkvmerge report this error: Error: Invalid track ID or language code in '-s '.
I don't really know where the mistake is!
Batchfile approach
You need to execute your command inside a for statement inside a batch file to be able to capture the output lines and process them further. Check for /? on the command line and the part with for /f and learn about "usebackq".
The key point is, that you need to escape several special characters from your command, if it is executed in the for statement and not on the command line prompt directly.
Try getting this piece to work and post your solution as update to your answer if you like. Then we can get to the second part of extracting the number.
I wrote the below code, which will extract the directory name along with the file name and I will use purge command on that extracted Text.
$ sear VAXMANAGERS_ROOT:[PROC]TEMP.LIS LOG/out=VAXMANAGERS_ROOT:[DEV]FVLIM.TXT
$ OPEN IN VAXMANAGERS_ROOT:[DEV]FVLIM.TXT
$ LOOP:
$ READ/END_OF_FILE=ENDIT IN ABCD
$ GOTO LOOP
$ ENDIT:
$ close in
$ ERROR=F$EXTRACT(0,59,ABCD)
$ sh sym ERROR
$ purge/keep=1 'ERROR'
The output is as follows:
ERROR = "$1$DKC102:[PROD_LIVE.LOG]DP2017_TMP2.LIS;27392 "
Problem here is --- Every time the directory length varies (Length may be 59 or 40 or some other value, but the directory and filename length will not exceed 59 characters in my system). So in the above output, the system is also fetching the Version number of that file number. So I am not able to purge the file along with the version number.
%PURGE-E-PURGEVER, version numbers not permitted
Any suggestion -- How to eliminate the version number from the output ?
I cannot use the exact length of the directory, as directory length varies everytime.... :(
The answer with F$ELEMENT( 0, ";", ABCD ) should work, as confirmed. I might script something like this:
$ ERROR = F$PARSE(";",ERROR) ! will return $1$DKC102:[PROD_LIVE.LOG]DP2017_TMP2.LIS;
$ ERROR = ERROR - ";"
$ PURGE/KEEP=1 'ERROR'
Not sure why you have the read loop. What you will get is the last line in the file, but assuming that's what you want.
While HABO explained it, some more explanations
Suppose I use f$search to check if a file exists
a = f$search("sys$manager:net$server.log")
then I find I it exists
wr sys$output a
shows
SYS$SYSROOT:[SYSMGR]NET$SERVER.LOG;9
From the help of f$parse I get
help lex f$parse arg
shows, among other things
`Specifies a character string containing the name of a field
in a file specification. Specifying the field argument causes
the F$PARSE function to return a specific portion of a file
specification.
Specify one of the following field names (do not abbreviate):
NODE Node name
DEVICE Device name
DIRECTORY Directory name
NAME File name
TYPE File type
VERSION File version number`
So I can do
wr sys$output f$parse(a,,,"DEVICE")
which shows
SYS$SYSROOT:
and also
wr sys$output f$parse(a,,,"DIRECTORY")
so I get
[SYSMGR]
and
wr sys$output f$parse(a,,,"NAME")
shows
NET$SERVER
and
wr sys$output f$parse(a,,,"TYPE")
shows
.LOG
the version is
wr sys$output f$parse(a,,,"VERSION")
shown as
;9
The lexicals functions can be handy, check it using
help lexical
it shows

I am trying to save a batch variable into a text file. I currently have this code:
#echo off
Set var=6
#echo %var%>txt.txt
For /f "tokens*" %%i in (txt.txt) do #echo %%i
Pause
It's supposed to save the 6 into the variable var and then write the variable in a text file. I want to do this to save user input into a text file so that when the batch program is terminated it will hold the variables.
There is a little problem with redirection. You are redirecting a "stream"; they are numbered 0-9. 0 is for "Standard Input" (STDIN), 1 is for "Standard Output" (STDOUT), 2 is for "Error Output" (STDERR).
If you use the redirection symbol > without a stream number, it defaults to "1".
So echo text>txt.txt is just an abreviation for echo text 1>txt.txt
Now it's getting tricky: echo 6>txt.txt won't echo "6" to the file, but tries to redirect "Stream 6" (which is empty) to the file. The Standard Output echo is off goes to the screen, because "Stream1" is not redirected.
Solution:
If you try to redirect a number or a string which ends with a number, just use a different syntax:
>txt.txt echo 6
Use the set command to get the contents of a file:
set /p var=<filename
Use the echo command to put into a file:
#echo Contents Of File > "FileName"
To append another line to the end of the file, use:
#echo Contents Of File >> "FileName"
Also, put the commands on separate lines or use '&&' between them on the same line.
