I do this in BASHecho test $1..expecting to get..test test..but I get..testIs this something possible to do? It would make my life easier since having a list files I could do something like mv a/b/test.py proj_copy/$1
Possible to reuse first argument of BASH line in the same line?
bash;command line;arguments;variable substitution
You can use history expansion$ echo test !#:^echo test testtest test$ echo a/b/test.py proj_copy/!#:^echo a/b/test.py proj_copy/a/b/test.pya/b/test.py proj_copy/a/b/test.py!#  The entire command line typed so far.:^    The first argumentYou could also use brace expansion$echo test{,}test test$echo {,proj_copy}/a/b/test.py/a/b/test.py proj_copy/a/b/test.py
