assume text file contains specific lines word order should altered. words (substrings) delimited single whitespaces. lines altered can identified first character (e.g., ">"). # cat test.txt >3 test foo bar baz foo bar qux >2 test foo bar baz >1 test foo bar qux what command (probably in awk ) use apply same ordering process across lines starting key character? # cat test.txt | sought_command >this test 3 foo bar baz foo bar qux >this test 2 foo bar baz >this test 1 foo bar qux here's 1 way using awk: awk 'sub(/^>/, "") { print ">"$3, $4, $2, $1; next } 1' file sub returns true (1) when makes substitution. 1 @ end shortest true condition, trigger default action { print } .
