ruby - Search and save a line containing a set of chars from an array -

-

i'm using readlines() read data 2 arrays, , need specific line.

problem:

i'm not sure string or array method use specific line containing '...blah' (my class' line/name of group.)

i prefer not save entire file content these 2 variables if possible. i'd rather "search" through file , save 2 specific lines need student_info , class_usernames.

student_info =  file.readlines ('/etc/passwd') class_usernames = file.readlines ('/etc/group')

you use detect on array:

student_info    = file.readlines('/etc/passwd').detect { |s| s.include?('...blah') } class_usernames = file.readlines('/etc/group').detect { |s| s =~ /\.\.\.blah/ }

and btw please not use whitespace between method name , parameter list.

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":...
