Hello Lee and Donovan.
Thank you for your information.
I tried the following
role :server, "user@server"
task :heredoctest, :roles => :server do
command = %Q{
cat<<EOS|wc -l
foo
foo
foo
EOS
}
run command
end
But execution failed.
The execution log is the following.
% cap heredoctest
* executing `heredoctest'
* executing "cat<<EOS|wc -l\\\n foo\\\n foo\\\n foo
\\\nEOS"
servers: ["server"]
[user@server] executing command
*** [err :: user@server] sh: line 4: warning: here-document at line 4
delimited by end-of-file (wanted `EOS')
*** [err :: user@server] wc:
*** [err :: user@server] foo
*** [err :: user@server] : No such file or directory
*** [err :: user@server]
*** [err :: user@server] wc:
*** [err :: user@server] foo
*** [err :: user@server] : No such file or directory

*** [err :: user@server] wc:
*** [err :: user@server] fooEOS
*** [err :: user@server] : No such file or directory
*** [err :: user@server]
** [out :: user@server] 0 total
command finished in 54ms
failed: "sh -c 'cat<<EOS|wc -l\\\n foo\\\n foo\\\n
foo\\\nEOS'" on user@server
Sincerely.
