查找文件的模式，使用该模式创建一个文件夹，然后将文件复制到该文件夹​​中-Bash脚本

Question

I have a task, to find the pattern of the file, create a folder with the pattern name and copy the file to that folder. I am able to create the folders.

---

folders=`find /Location -type f -name "*.pdf" -printf "%f\n" | cut -f 1 -d '_' | sort -u`
for i in $folders
do
    mkdir -p /LocationToCreateTheFolder/$i
done

---

Not able to go further on how to copy the files.

Answer 1

也许尝试？

for i in $folders do mkdir -p /LocationToCreateTheFolder/$i && cp ./$i.pdf ./$i/ 

Answer 2

This will do the finding and the copying:

find Location -type f -name '*.pdf' -exec bash -c 'f=${1##*/}; d="LocationToCreateTheFolder/${f%%_*}"; mkdir -p "$d" && cp "$1" "$d"' None {} \;

This is safe for difficult file names even ones that contain spaces, tabs, or newlines in their names.

How it works

• find Location -type f -name '*.pdf' -exec bash -c '...' None {} \\;

  This will find the pdf files under directory Location and, for each one found, the bash commands inside '...' will be executed with $1 set to the name of the file found. ( $0 is set to None . We don't use $0 .)

• f=${1##*/}

  This removes the directory names from the name of the file. This is an example of prefix removal : everything in $1 up to and including the last / is removed.

• d="LocationToCreateTheFolder/${f%%_*}"

  This creates the name of the directory to which we want to send the file.

  ${f%%_*}" is an example of suffix removal . Everything in $f from the first _ and after is removed.

• mkdir -p "$d" && cp "$1" "$d"

  This makes sure that the directory exists and then copies the file to it.
