Linux 查找重复项将附加文件发送到新目录

Question

I've been struggling with this,part of a job interview I found online but cant figure it out.

**Obtain a list of paths to all PDF and pdf files within the source directory.

For every file in this list Check to see if there is a corresponding doc file in the same directory.

If there is do nothing

If there is not

Check to see if there is already a PDF file in the target directory with this name.

If there is not, copy the PDF file to the target directory as is.

If there is and it is not identical, copy the PDF file to the target directory but append “_” to the filename.**

Got the pdf with find but cant loop the files.

find ../mnt -iname "*.pdf" 

Answer 1

there are lots of ways to do this but starting with your find command

for i in $(find ../mnt -iname "*.pdf"); do z=$(basename -s .pdf $i); echo $z;done

this will print out a list of filenames with the suffixes removed. Then it is simple to do something like

if [ -e "..mnt/$z.doc" ]; then

To check if the doc file is there
