我现在需要删除环境变量里面 包含jdk1.6字串的路径，请问怎么处理好！


最后结果为
/home/kaober/kaober/MT6582_L/main/out/host/linux-x86/bin:/home/kaober/kaober/MT6582_L/main/prebuilts/gcc/linux-x86/arm/arm-linux-androideabi-4.8/bin:/home/kaober/kaober/MT6582_L/main/prebuilts/gcc/linux-x86/:/home/kaober/kaober/MT6582_L/main/prebuilts/gcc/linux-x86/arm/arm-eabi-4.8/bin:/home/kaober/kaober/MT6582_L/main/development/scripts:/home/kaober/kaober/MT6582_L/main/prebuilts/devtools/tools:/home/kaober/kaober/MT6582_L/main/prebuilts/android-emulator/linux-x86_64:/usr/lib/jvm/java-7-openjdk-amd64/jre/bin/:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games
