中午“夜深人静”时分，写了个版本控制脚本，放在代码编译的开头，以后再也不用手动修改软件的版本号了，爽到没朋友有没有？

#!/bin/bash

tmp=`sed -n 's/.*VERSION.*"\(.*\)"/\1/p' version.h`

echo tmp



cnt=`echo $tmp | tr . "\n" | wc -l`



a=0;b=0;c=0



if [ $cnt == 3 ]; then

    a=`echo $tmp|sed -n 's/\(.*\)\.\(.*\)\.\(.*\)/\1/p'`

    b=`echo $tmp|sed -n 's/\(.*\)\.\(.*\)\.\(.*\)/\2/p'`

    c=`echo $tmp|sed -n 's/\(.*\)\.\(.*\)\.\(.*\)/\3/p'`

else

    b=`echo $tmp|sed -n 's/\(.*\)\.\(.*\)/\1/p'`

    c=`echo $tmp|sed -n 's/\(.*\)\.\(.*\)/\2/p'`

fi



echo verionName=$tmp

echo a=$a,b=$b,c=$c



sed -i 's/\(.*VERSION.*"\)[^"]*"/\1'$((a+0))'.'$((b+0))'.'$((c+1))'"/' version.h



x=`printf "%03d\n" $((a+0))`

y=`printf "%03d\n" $((b+0))`

z=`printf "%03d\n" $((c+1))`
