bash - How to pipe a here-document through a command and capture the result into a variable? -

-

Now this value is required on stdout. How can I capture it in a variable, so that I can use it in the other script?

Prerequisites:

  • The script needs all in one file.
  • If possible, I do not want to write a temporary file

. 

  #! / Bin / bash cat & lt; & Lt; EOF | XSLTProx - ../pom.xml | Tail-1 & lt ;? XML version = "1.0"? & Gt; & Lt; Xsl: stylesheet version = "1.0" xmlns: xsl = "http://www.w3.org/1999/XSL/transform" & gt; & Lt; Xsl: template match = "/" & gt; & Lt; Xsl: Select Value = "/ Project / Version" /> & Lt; / Xsl: Templates & gt; & Lt; / XSL: stylesheet & gt; EOF

It starts working (based on the answer to Ignaceo). Using a subshell here-papers are pipe right in the XSLTproc, while it is crossed even after tail. 

  VERSION = $ ((xsltproc - ../pom.xml | tail -1) & lt; EOF   gt;

oracle - The fastest way to check if some records in a database table? -

-
I have a big table to work with. I have to see that there are some records whose parent_id is equal to my passing value. Currently I do this by implementing "my_table using select count (*) where parent_id =: id"; If the result> 0, it means that they exist. Because this is a very large table, and I do not care what the actual number of records present, I just want to know if it exists, so I think count (*) Bit is disabled. How do I apply this requirement most quickly? I'm using Oracle 10. # Tips for Hibernation & amp; Tricks It suggests writing in such a way: Integer number = (integer) session .createQuery ("Select Count (*) to ...."). UniqueResult (); I do not know what is the magic of the unique rule? Why does it fast? To compare, select "1 from mytable where parent_id = passId and rowrum", which is more efficient? If you are not interested in the number of records, then there is an EXISTS query one: Select 'y'
