I have a bunch of text files with the name
foo_bar_abc_1_01_geh_original.in
foo_bar_abc_1_02_geh_original.in
foo_bar_abc_1_03_geh_original.in
...
...
foo_bar_abc_1_1000_geh_original.in
I would like to copy (and keep the original files) each file and paste to different names (in the same folder) like,
foo_bar_abc_1_01_geh_copy.in
foo_bar_abc_1_02_geh_copy.in
foo_bar_abc_1_03_geh_copy.in
...
...
foo_bar_abc_1_1000_geh_copy.in
How can I do this using a simple script?
