AWK to print field $2 first, then field $1
Maybe your file contains CRLF terminator. Every lines followed by \r\n.
awk
recognizes the $2
actually $2\r
. The \r
means goto the start of the line.
{print $2\r$1}
will print $2
first, then return to the head, then print $1
. So the field 2 is overlaid by the field 1.
Use a dot or a pipe as the field separator:
awk -v FS='[.|]' '{
printf "%s%s %s.%s\n", toupper(substr($4,1,1)), substr($4,2), $1, $2
}' << END
[email protected]|com.emailclient.account
[email protected]|com.socialsite.auth.account
END
gives:
Emailclient [email protected]
Socialsite [email protected]
A couple of general tips (besides the DOS line ending issue):
cat
is for concatenating files, it's not the only tool that can read files! If a command doesn't read files then use redirection like command < file
.
You can set the field separator with the -F
option so instead of:
cat foo | awk 'BEGIN{FS="|"} {print $2 " " $1}'
Try:
awk -F'|' '{print $2" "$1}' foo
This will output:
com.emailclient.account [email protected]
com.socialsite.auth.accoun [email protected]
To get the desired output you could do a variety of things. I'd probably split()
the second field:
awk -F'|' '{split($2,a,".");print a[2]" "$1}' file
emailclient [email protected]
socialsite [email protected]
Finally to get the first character converted to uppercase is a bit of a pain in awk
as you don't have a nice built in ucfirst()
function:
awk -F'|' '{split($2,a,".");print toupper(substr(a[2],1,1)) substr(a[2],2),$1}' file
Emailclient [email protected]
Socialsite [email protected]
If you want something more concise (although you give up a sub-process) you could do:
awk -F'|' '{split($2,a,".");print a[2]" "$1}' file | sed 's/^./\U&/'
Emailclient [email protected]
Socialsite [email protected]
The awk is ok. I'm guessing the file is from a windows system and has a CR (^m ascii 0x0d) on the end of the line.
This will cause the cursor to go to the start of the line after $2.
Use dos2unix or vi with :se ff=unix
to get rid of the CRs.
