Hello,

I don’t understand what > mean in the spec file.

https://build.opensuse.org/package/view_file/graphics/freeimage/freeimage.spec?expand=1

This part

> Source/FreeImage/PluginG3.cpp
> Source/FreeImageToolkit/JPEGTransform.cpp

It is the same as rm?

Thanks.

#2

clear files which cannot be built due to dependencies on private headers

(see also unbundle patch)

It disables the G3 Fax Loader and the JPEG lossless transformations plugins

> Source/FreeImage/PluginG3.cpp
> Source/FreeImageToolkit/JPEGTransform.cpp

Read the comment.
It writes “nothing” to the files…
See > or >> for operator in bash

Thanks, I found out that it remove the inside content, similar to truncate, I thought that clear file mean the same as delete.

a > xxx = means: delete the content of xxx file and write a into that file, if the file does not exist, create it and write a as content in it.
a >> xxx = means: write a at the end of the content of file xxx, if the file does not exist, create it and write a as content in it.

Wrong. a is executed and its output replaces/is appended to file.
