\nAlthough the redirection operator traditionally appears at the end\nof a command line, there is no requirement that it do so.\nAll of these commands are equivalent:\n<\/p>\n

\necho A B>C\necho A>C B\necho>C A B\n>C echo A B\n<\/pre>\n
\nAll of them echo “A B” to the file “C”.\n<\/p>\n
\nYou can use this trick to avoid\n\nthe redirection problem we discussed last time<\/a>.\nWe saw that writing\n<\/p>\n
\nset message=Meet at 2\necho %message%>schedule\n<\/pre>\n
\ninadvertently interprets the “2” as part of the redirection operator.\nOne solution was to insert a space:\n<\/p>\n
\necho %message% >schedule\n<\/pre>\n
\nbut this assumes that the space won’t cause a problem.\nIf you’re in a case where that space will indeed cause a problem,\nyou can use the trick above to move the redirection operator\nto a location where it won’t cause any trouble:\n<\/p>\n
