   I'd put the list of commands in a shell script; e.g.,

# import_files.R
read_csv("file1.csv", header = T, sep = ',')
read_csv("file2.csv", header = T, sep = ',')

etc.

   Then, within a R session, run

source("/full/path/to/import_files.R")

or, on the command line,

R CMD BATCH /full/path/name/to/import_files.R

   You'll still need to list all the files individually unless you use a
loop. I've not tried that so someone more experienced will advise you on
that.
