Copy Code code as follows:
find/root/-name ' *.sql ' |awk ' a=$0;sub (/sql$/, "TXT", $); print "MV", a,$0} ' |bash
find/root/-maxdepth 1-name ' *.sql ' |awk ' {a=$0;sub (/txt$/, "SQL", $); System ("MV" "" A "" $)} "
2, for Loop
Copy Code code as follows:
For SQL in ' Find/root-name ' *.sql ';d o mv $sql ' echo $sql |sed ' s/sql/txt/';d one
