no man. The requirement is this.
while running an application I have to print STDERR messages both on screen(STDOUT) and file at the same time while the normal STDOUT messages should be on screen only. |

Use this:
Script is "cmd" Code:
#!/bin/sh echo "This is Standard Out" echo "This is Standard Error" >&2 Code:
((./cmd 3>&1 1>&2 2>&3) | tee /dev/tty) > err.log Code:
((./cmd 3>&1 1>&2 2>&3) | tee /dev/tty) > err.log This is Standard Out This is Standard Error Code:
cat err.log This is Standard Error   |
