Is there a way for a bash
shell program, that takes a command-line argument x
, that will make x
(C program) processes start?
.
It's fairly simple:
#!/bin/bash
$1
If you want to pass the rest of the parameters as parameters to the function, do this:
$@
(ie foo.sh echo hi
executes echo hi
)
If you want to steal some parameters and pass others, use shift
:
param1=$1
shift
echo $@ # contains parameters 2+
#!/bin/bash
(( $# != 1 )) && echo "Usage: $0 num" && exit -1
for (( c=1; c<=$1; c++ ))
do
./run_c_program &
done
wait
$1
represents the first command line argument $#
represents the number of arguments $0
is the name of the script run_c_program
is the executable of the c program &
the c programs are executed in the background wait
the scripts waits for the c programs to terminate (optional) 您可以尝试使用system
功能
system("./script.sh");
