Hi all, Can one export/set some variables for an already running shell from other shell ? Is there any command where i can specify env=value & shell process id ? This is similar to sending signals from one to another process. We have one program, which prints some debugging information when a env variable is set. During execution, first a new shell is created & then program is executed. Sometimes that program gets stuck somewhere without printing anything. If i set the env variable & then execute, the messages will come from start of execution. I want some mechanism so that when program is stuck, i can set that env variable which will enable printing debugging information. Is this possible using some command ? OR how to do this ? This question is somewhat out of topic(not related to kernel). But, still help will be appreciated.
