How to use the command line to quickly find the Jar file where the Class file is located. For this problem, this article introduces the corresponding analysis and solution in detail, hoping to help more small partners who want to solve this problem find a simpler and easier way.

Because jar command to find class file speed is relatively slow, I personally try to use 7z.exe,7z.dll, combined with batch processing, the effect is very good.

See examples:

for %i in (dir/b/s *.jar) do 7z l %i | findstr XDatabase.class

Results:

D:\shared\xsql>for %i in (dir/b/s *.jar) do 7z l %i |findstr XDatabase.class D:\shared\xsql>7z l dir/b/s | findstr XDatabase.class D:\shared\xsql>7z l db2jcc.jar | findstr XDatabase.class D:\shared\xsql>7z l db2jcc_license_cu.jar | findstr XDatabase.class D:\shared\xsql>7z l jconn3.jar | findstr XDatabase.class D:\shared\xsql>7z l jodbc.jar | findstr XDatabase.class D:\shared\xsql>7z l jTDS3.jar | findstr XDatabase.class D:\shared\xsql>7z l mlscript.jar | findstr XDatabase.class D:\shared\xsql>7z l msbase.jar | findstr XDatabase.class D:\shared\xsql>7z l mssqlserver.jar | findstr XDatabase.class D:\shared\xsql>7z l msutil.jar | findstr XDatabase.class D:\shared\xsql>7z l mysql-connector-java-5.1.6-bin.jar | findstr XDatabase.class D:\shared\xsql>7z l ojdbc14.jar | findstr XDatabase.class D:\shared\xsql>7z l postgresql-8.4-701.jdbc4.jar | findstr XDatabase.class D:\shared\xsql>7z l sqlite.jar | findstr XDatabase.class D:\shared\xsql>7z l sqlitejdbc-v056-zentus.jar | findstr XDatabase.class D:\shared\xsql>7z l sqljdbc.jar | findstr XDatabase.class D:\shared\xsql>7z l ULjDatabaseTransfer.jar | findstr XDatabase.class D:\shared\xsql>7z l UltraLiteJ.jar | findstr XDatabase.class D:\shared\xsql>7z l UltraLiteJ12.jar | findstr XDatabase.class [b]D:\shared\xsql>7z l xsql.jar | findstr XDatabase.class 2010-12-24 21:05:40 ..... 30863 14443 [/b]com\sean\db\XDatabase.class

The last row shows the final result.

Write the above logic into batch processing:

@echo off SETLOCAL set WHICH_CLASS=%1 echo WHICH_CLASS=%WHICH_CLASS% for /F %%i in ('dir /A:-D /S /B *.jar') do 7z l %%i | findstr %WHICH_CLASS% && echo %WHICH_CLASS% found in: "%%i" echo "Finished class finding... " echo "======================================" ENDLOCAL

Run the command:

findclass com\\sybase\\afx\\util\\StringUtil.class WHICH_CLASS=com\\sybase\\afx\\util\\StringUtil.class 2012-02-27 13:14:36 ..... 15230 5915 com\sybase\afx\util\StringUtil.class com\\sybase\\afx\\util\\StringUtil.class found in: "U:\target\lib\ext\sup-client.jar" 2012-02-27 13:14:36 ..... 15230 5915 com\sybase\afx\util\StringUtil.class com\\sybase\\afx\\util\\StringUtil.class found in: "U:\target\lib\ext\sup-server-rt.jar" "Finished class finding... " "======================================"

It is easy to get the final result. Given enough time, we can even modify the source code of 7z so that it lists the full path of the file directly, so that the final file can be found directly using 7z.
