Shell script recursive function - traverse each directory to operate

. modify.func //import each function

modify .suf1 .suf2 //call function

put the current directory All file names ending with .suf1 are modified to end with .suf2, such as: modify .pc .ec

Recursively implements the subdirectories of the subdirectories. . . .
