Bash script to insert code from one file at a specific location in another file?
- by Kurtosis
I have a fileA with a snippet of code, and I need a script to insert that snippet into fileB on the line after a specific pattern.
I'm trying to make the accepted answer in this thread work, but it's not, and is not giving an error so not sure why not:
sed -e '/pattern/r text2insert' filewithpattern
Any suggestions?
pattern (insert snippet on line after):
def boot {
also tried escaped pattern but no luck:
def\ boot\ {
def\ boot\ \{
fileA snippet:
LiftRules.htmlProperties.default.set((r: Req) =>
new Html5Properties(r.userAgent))
fileB (Boot.scala):
package bootstrap.liftweb
import net.liftweb._
import util._
import Helpers._
import common._
import http._
import sitemap._
import Loc._
/**
* A class that's instantiated early and run. It allows the application
* to modify lift's environment
*/
class Boot {
def boot {
// where to search snippet
LiftRules.addToPackages("code")
// Build SiteMap
val entries = List(
Menu.i("Home") / "index", // the simple way to declare a menu
// more complex because this menu allows anything in the
// /static path to be visible
Menu(Loc("Static", Link(List("static"), true, "/static/index"),
"Static Content")))
// set the sitemap. Note if you don't want access control for
// each page, just comment this line out.
LiftRules.setSiteMap(SiteMap(entries:_*))
// Use jQuery 1.4
LiftRules.jsArtifacts = net.liftweb.http.js.jquery.JQuery14Artifacts
//Show the spinny image when an Ajax call starts
LiftRules.ajaxStart =
Full(() => LiftRules.jsArtifacts.show("ajax-loader").cmd)
// Make the spinny image go away when it ends
LiftRules.ajaxEnd =
Full(() => LiftRules.jsArtifacts.hide("ajax-loader").cmd)
// Force the request to be UTF-8
LiftRules.early.append(_.setCharacterEncoding("UTF-8"))
}
}
