linux - I cannot print color escape codes to the terminal -

-

when run script:

fn main() {     // \033[0;31m <- red     // \033[0m <- no color     println!("\033[0;31mso\033[0m") }

i expect get

so #in red letters

however, get:

33[0;31mso33[0m

when ran similar script in go or python, expected output. going on? missing? how fix this?

i using:

$ rustc --version rustc 1.3.0 (9a92aaf19 2015-09-15) $ lsb_release -a no lsb modules available. distributor id: ubuntu description:    ubuntu 14.04.3 lts release:    14.04 codename:   trusty

rust 1.3.0 not seem support octal escape strings such \033. instead, can use hexadecimal escape strings \x1b.

fn main(){   println!("\x1b[0;31mso\x1b[0m") }

apache - Error with PHP mail(): Multiple or malformed newlines found in additional_header -

-
suddenly have started receiving above error without changes having been made script. host 1and1 (i know...) the script still works fine on different server, , suspicion there must have been server config change has lead this, although hosts plead ignorance. there's no information on above error @ in google can find - have ideas? server running apache if helps. had similar problem. came out of blue. no php code changed. what changed: php upgraded 5.5.25-1 5.5.26. a security risk in php mail() function has been fixed , newlines in additional_headers allowed no more. because newlines mean: starts email message (and surely don't want inject newlines through headers followed evil message). what have worked fine, e.g. having newlines after headers or passing whole message additional_headers , function no more. solution : sanitize headers. no multiple newlines in additional_headers argument. these count "multiple or malformed newlines":...
