Run a command for specific amount of time with an auto key press
Hi,
I have been trying to do a small fun project for myself.
I want to run a command for 45 seconds.
And to get the final output of this command, the script requires I push the "q" key on my keyboard and then the final output file becomes available.
I tried the following script. But it is not taking the "q" key and also runs for more than 45 seconds. I was wondering if someone could lead me on how to press a key automatically inside a bash script.
Thanks

Hi,
Is there a command to print one character x amont of times?
I need for example 10 comma's (,,,,,,,,,,). Instead of creating a loop, I was wondering if there is a way to do this with sed or awk?

rbash
RBASH(1) General Commands Manual RBASH(1)NAME
rbash - restricted bash, see bash(1)RESTRICTED SHELL
If bash is started with the name rbash, or the -r option is supplied at invocation, the shell becomes restricted. A restricted shell is
used to set up an environment more controlled than the standard shell. It behaves identically to bash with the exception that the follow-
ing are disallowed or not performed:
o changing directories with cd
o setting or unsetting the values of SHELL, PATH, ENV, or BASH_ENV
o specifying command names containing /
o specifying a file name containing a / as an argument to the . builtin command
o specifying a filename containing a slash as an argument to the -p option to the hash builtin command
o importing function definitions from the shell environment at startup
o parsing the value of SHELLOPTS from the shell environment at startup
o redirecting output using the >, >|, <>, >&, &>, and >> redirection operators
o using the exec builtin command to replace the shell with another command
o adding or deleting builtin commands with the -f and -d options to the enable builtin command
o using the enable builtin command to enable disabled shell builtins
o specifying the -p option to the command builtin command
o turning off restricted mode with set +r or set +o restricted.
These restrictions are enforced after any startup files are read.
When a command that is found to be a shell script is executed, rbash turns off any restrictions in the shell spawned to execute the script.
