翻译强力驱动I have a Unix shell script test.sh. Within the script i would like to invoke another shell and then execute the rest of the commands in the shell script from the child shell and exit
To make it clear:
test.sh#! /bin/bash /bin/bash /* create child shell */ <shell-command1> <shell-command2> ...... <shell-commandN> exit 0What my intention is to run the shell-commands1 to shell-commandN from the child shell. Kindly tell me how to do this
You can setup in a group, like.
#!/bin/bash ( Command1 Command2 etc.. ) subshell() { echo "this is also within a subshell" } subshell( and ) creates a subshell in which you run a group of commands, otherwise a simple function will do. I don't know if ( and ) is POSIX compatible.
Update: If I understand your comment correctly, you want to be using -c option with bash, like.
/bin/bash -c "Command1 && Command2...." &From http://tldp.org/LDP/abs/html/subshells.html here is an example:
#!/bin/bash # subshell-test.sh ( # Inside parentheses, and therefore a subshell . . . while [ 1 ] # Endless loop. do echo "Subshell running . . ." done ) # Script will run forever, #+ or at least until terminated by a Ctl-C. exit $? # End of script (but will never get here).
