Identify Java software installed.

[d3v]

Hello all - I hope someone can help me code this...

objective is to identify all JAVA software installed so I can uninstall them from a host (using script)

i have a text file output which i am generating in cmd prompt (bat file)

wmic product get description | findstr /i java >remove_java.cmd

problem is the output file remove_java.cmd - it generates the file with trailing spaces in the output for each name it picks up
for example:

Java 8 Update
Java 8 Update 281 (64-bit)
Java SE Development Kit 8 Update 281 (64-bit)

all above three lines have trailing white spaces which I would like to remove.

what command can I use.

and as an addition I would like to update the line to following - so I can use it to remove the installs via command line.

WMIC Product Where "description='Java 8 Update 281'" Uninstall
WMIC Product Where "description='Java 8 Update 281 (64-bit)'" Uninstall
WMIC Product Where "description='Java SE Development Kit 8 Update 281 (64-bit)" Uninstall

Wmic returns a trailing carriage return. to resolve this, use a nested for loop to strip it from the output when generating the output.

Code: Select all

wmic product get description | findstr /i java >remove_java.cmd

Don't do it like that, the official recommendation is not to use Win32_Product, (for which Product is a WMIC alias).

When Win32_Product is enumerated, it actually performs a full status check on each product. This not only affects your script time, on top of that of the already slow WMIC utility, but can also mean that repairs/modifications are made to the enumerated products too.

I would advise that you use the reg.exe utility to enumerate the subkeys of HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Installer\Products instead. The resulting batch file may be more complex codewise, but it would be safer, and would run much quicker.

agreed with the points laid out...will code accordingly.

in the meantime, found a one line code which uninstalled all JAVA installs in one line - and no coding was required.

wmic product where "name like '%%Java%% Update%%'" call uninstall

tested and it worked perfectly....but will work on develing further using the reg.

thanks all.

The system cannot find the file '  wmic product get description | findstr /lic: "java" .

It is missing the closing single quote.
The syntax from the help file.

Code: Select all

FOR /F ["options"] %variable IN ('command') DO command [command-parameters]
