试试这个 :
#!/bin/bash
# max seconds before mail alert
MAX_SECONDS=3600
# running the command in the background and get the pid
command_that_takes_a_long_time & _pid=$!
sleep $MAX_SECONDS
# if the pid is alive...
if kill &>/dev/null -0 $_pid; then
mail -s "script $0 takes more than $MAX_SECONDS" user@domain.tld < /dev/null
fi
我们在后台运行命令,然后在 // 中休眠 MAX_SECONDS 并在进程占用的时间超过允许的时间时通过电子邮件发出警报。
最后,根据您的具体要求:
#!/bin/bash
MAX_SECONDS=3600
alerter(){
bash "$1" & _pid=$!
sleep $MAX_SECONDS
if kill &>/dev/null -0 $_pid; then
mail -s "$2 takes more than $MAX_SECONDS" user@domain.tld < /dev/null
fi
}
for each in /some_folder/*.sh; do
alerter "$each" &
wait $_pid # remove this line if you wou'd like to run all scripts in //
done
