bash-将文件复制并重命名到更高的目录，再复制到新的文件类型

Question

I am still learning bash, but this should be easy. I want to copy a file from a temp folder to a higher directory, and change the name.

home/temp/oldfile to home/newfile.txt

oldfile has no specific file type, and it's name is adjusted on a daily basis. So, I would like to copy whichever file is in home/temp and paste it as .txt. The temp folder contains only 1 file.

Command so far

cp /home/temp/. /home/newfile.txt -R

I then get the error cp: omitting diretory '/home/temp/.'

Any ideas? Thanks.

Answer 1

you should replace . with * :

cp /home/temp/* /home/newfile.txt

no need for the -R option; since you are copying only one file.
