Shell 脚本将文件从一个目录复制到另一个目录

Question

I am trying to copy a file from a dir to another directory location using regx * like below

cp /location1/abc_* /location/xyz_

Its failing to copy because In location1 there are many files with abc_123 abc_234 like these.

Seems like command get confuse to copy which file as xyz_

I want to copy only the file which is recent abc_ file. Is there any way to achieve this requirement?

You can iterate over the glob to select the most recent file, then copy that one file. (Every file compares as "newer" than a non-existent file

newest=
for f in /location1/abc_*; do
    [[ $f -nt $newest ]] && newest=$f
done

cp "$newest" /location/xyz_/
