Assuming your files are in /*.txt:

   names <- dir( patt="[.]txt$" )
   do.call( "rbind", lapply( names, read.table ) )

: in Bash
: ls > names
: in R
: names<-scan(names...)
: With rep() and data.frame() construct a series of read.table() commands, 
: which you write to a file and execute them with source().

: from all imported data frames in a single vector avoiding the manual writing 
: of all the imported data frame names.
: Thanks in advance, Miha
