to be very precise

when you do a ls -l if the first column of the file permissions is a -, then that file is a regular file.
I dont really think that it should be a text or data file, it can be a binary file as well, or for that matter any other file, just the the first column of ls -l should be - Smilie

correct me if i m wrong

for eg
-rw-rw-r-- 1 username group 141 Nov 21 14:08 log

here the first column of -rw-rw-r-- is a -, it means it is a regular file.

NAME
colrm -- remove columns from a file SYNOPSIS
colrm [start [stop]] DESCRIPTION
The colrm utility removes selected columns from the lines of a file. A column is defined as a single character in a line. Input is read from the standard input. Output is written to the standard output. If only the start column is specified, columns numbered less than the start column will be written. If both start and stop columns are spec- ified, columns numbered less than the start column or greater than the stop column will be written. Column numbering starts with one, not zero. Tab characters increment the column count to the next multiple of eight. Backspace characters decrement the column count by one. ENVIRONMENT
The LANG, LC_ALL and LC_CTYPE environment variables affect the execution of colrm as described in environ(7). EXIT STATUS
The colrm utility exits 0 on success, and >0 if an error occurs. SEE ALSO
awk(1), column(1), cut(1), paste(1) HISTORY
The colrm command appeared in 3.0BSD. BSD
