Today, I will talk to you about how to use shell script to solve the problem of file backup, many people may not know much about it. In order to make you understand better, the editor summarizes the following content for you. I hope you can get something according to this article.

The documents on the computer already have more than 50 gigabytes, in which there are some things, as well as a lot of photos and videos, and so on. These photos really take up too much space, need to be scaled down and stored, backup, do not need so high definition, the previous 50% will be fine. The requirements are simple:

Compress the JPG file

Other files have updated copies, but before there is no updated copy, I wrote a script in shell, which I think is too long. Recently, I have also been learning shell scripts, which can be solved with pipes:

DstDir=/cygdrive/g/test/srcDir=/cygdrive/h/doccd $srcDirfind | sed-r "s: ^ (. * (jpg | JPG)) $: cp-v-- parents" 1 "" $dstDir "& & convert-resize 50% x50%" $dstDir1 "" $dstDir1 ": G" | sed-r "s: ^ (. *) $: cp-vu-parents" 1 "$dstDir": G "| sh-verbose

The principle of the script is simple, replace it with sed and OK it.
