我知道,要删除所有作业/任务,您只需使用:
crontab -r;
但是如果有多个作业/任务,您如何列出它们,然后删除所选的任务?
#!/usr/bin/env bash
# Array of cron job entries
typeset -a cron_entries
# Store the contab jobs into an array
mapfile -t cron_entries < <(crontab -l | grep -vE '^(#.*|[[:space:]]*)$')
if (( ${#cron_entries[@]} > 0 )); then
# List all the jobs
echo "Here are the current cron jobs:"
printf 'Index\tJob entry\n'
for ((i=0; i<"${#cron_entries[@]}"; i++)); do
printf '%4d\t%s\n' $i "${cron_entries[i]}"
done
# Prompt user for job index or exit
read -p $'\nPlease choose a job index to delete, or an invalid index to abandon: ' -r answer
# If answer is a positive integer and within array bounds
if [[ "$answer" =~ ^[0-9]+$ ]] && (( answer < ${#cron_entries[@]} )); then
# Show deleted entry
printf '\nDaleting:\t%4d\t%s\n' "$answer" "${cron_entries[answer]}"
# Delete the selected cron entry
unset cron_entries["$answer"]
# Send the edited cron entries back to crontab
printf '%s\n' "${cron_entries[@]}" | crontab -
else
printf '\nAborted with choice %q\nNo job deleted\n' "$answer"
fi
else
printf 'There is no cron job for user: %s\n' "$USER"
fi
crontab -e
,它应该在系统编辑器中打开所有cron任务,然后删除特定的条目并保存并退出。干杯编辑:添加从脚本中删除
您可以执行类似-crontab -l | grep -v '<SPECIFICS OF YOUR SCRIPT HERE>' | crontab -
根据您的脚本。试试看,让我知道它是否有效
