I want to conc

Answer 1

This works in Bash:

for f in *.txt; do cat $f; echo; done

In contrast to answers with >> (append), the output of this command can be piped into other programs.

Examples:

• for f in File*.txt; do cat $f; echo; done > finalfile.txt
• (for ... done) > finalfile.txt (parens are optional)
• for ... done | less (piping into less)
• for ... done | head -n -1 (this strips off the trailing blank line)
