The File Replace String activity finds and replaces a string in a file on a Linux or UNIX computer.
This activity replaces an SSH activity by the same name available
in releases prior to Istanbul. If you have a workflow created in a previous version that
uses the deprecated activity, your workflow will continue to work normally after upgrading
to Istanbul. However, all new workflows must use the custom version of this activity. This
activity was built with the SSH activity template, which gives workflow administrators the ability to store
input and output variables in the databus.
