Shellscript遍历所有文件并调整符号链接

Question

I was trying to get libetpan up and running on iOS, however there seemed to be something wrong with their setup shell script (problem explained in more detail here).. but basically I got a folder with a long list of symlinks pointing to nowhere ie

mhdriver_types.h -> ../../src/driver/implementation/mh/mhdriver_types.h

when in fact it should be

mhdriver_types.h -> ../../../src/driver/implementation/mh/mhdriver_types.h 

I want to write a shell script that loops through all the symlinks, deleting each, then recreating a symlink for it to the same former destination only one subdirectory deeper.. basically doing what i did in the example to all the files..

any ideas?

Answer 1

inspired by anishsane's answer i got this code that works:

for name in $(find . -type l); do
    tgt=`readlink "$name"`
    ln -sf ../$tgt
done

Answer 2

尝试：

find $DIR_PATH -type l | while read x; do tgt=`readlink "$x"`; ln -sf ../$tgt $x; done
