Hi consider the source file
R|field1|field2
using the print statement in awk prints it as
R field1 field2
Is there an easier way to print the whole line in its original format (i.e. with | delimiters) than doing print $1"|"$2"|"$3 ??
Thanks

snsplit
snsplit,v0.3.8(8) System Manager's Manual snsplit,v0.3.8(8) NAME
snsplit - split an article stream into individual articles SYNOPSIS
snsplit [-r] [field... -] prog... DESCRIPTION
snsplit reads an article stream from descriptor 0 and splits it into separate articles, invoking prog... on each, with the article ava- iable on descriptor 0. This is useful as a quick-and-dirty way of filtering an article stream. The incoming article stream is expected to be in wire format, with lines ending in CRLF, leading dots doubled, and delimited by a dot on a line by itself. The article presented to prog... will have lines that end in a bare newline, will have all header lines unfolded, leading dots will be unstuffed, and the article will be terminated by end-of-file. ARGUMENTS
prog... is the program (with arguments) to run on each article. If prog... exits with any kind of failure, snsplit aborts. field...- are optional header field names. If these are specified, the value of the first header field of that name will be exported into the environment. This field... list must be terminated by the hyphen. See also ENVIRONMENT below. OPTIONS
-r Expect input articles in rnews batch format instead. ENVIRONMENT
snsplit sets some environment variables. If the environment already contains these variables, they will be overwritten. SEQUENCE If already set to a positive value, it is incremented for the first article. If it isn't set, is set to one for the first article. Thereafter it is incremented for each subsequent article. The value is always a 6-digit number with leading zeroes, and it can roll over. BYTES contains the size of the current article. HEAD_LINES The number of lines in the head of the article, excluding the blank separator line. BODY_LINES The number of lines in the body of the article, excluding the blank separator line. FLD_FIELD If any fields are specified on the command line, where field is the name of an article header field, then FLD_FIELD will be set to the value of field, where FIELD is the same as field but with lower case characters changed to upper case, and all hyphens changed to underscores. Confusing? If field is message-id, then FLD_MESSAGE_ID will be set to the value of the first Message-ID field in the current article, if there is one. EXIT CODES
snsplit exits 0 on success, 1 on usage error, 2 on system error, and 3 on article format error. If prog... exits with other than 0, snsplit will also exit that value. N.B. Harold Tay snsplit,v0.3.8(8)
