awk search and replace and overwrite file
hi,

i am doing

Code:
awk '{gsub("hello", "bye", $0); print}' test.dat

but I want to actually store the results of this global change into the file test.dat itself, i.e. I don't want the results to come to stdout, I want the results to overwrite the initial file

how can I do this?

thanks

tpm_selftest(8) 					      System Manager's Manual						   tpm_selftest(8)

							  TPM Management - tpm_selftest

NAME

       tpm_selftest - request TPM perform selftest and report

SYNOPSIS

       tpm_selftest [OPTION]

DESCRIPTION

       tpm_selftest requests that the system's TPM perform a self test (via the TPM_SelfTestFull API) and report the results. The --results option
       reports the outcome of the last self test operation without requesting that another test be executed. If the TPM fails the self test, it
       enters failure mode where no commands are accepted. The results are reported in a manufacturer specific format. The TPM's self test is
       always executed automatically at every boot.

       -h, --help
	      Display command usage info.

       -v, --version
	      Display command version info.

       -l, --log [none|error|info|debug]
	      Set logging level.

       -r, --results
	      Report results only.
