可以执行二进制,但不能使用"源"

Question

试着开始watch jobs工作.这很棘手,因为jobs报告当前shell拥有的作业,并watch创建另一个shell.因此我想运行. watch jobs或source watch jobs,但我收到此错误:

-bash: source: /usr/bin/watch: cannot execute binary file

这是输出file /usr/bin/watch:

/usr/bin/watch: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.15, BuildID[sha1]=0xe207fd209faf781a58f5f30922c99da759bd3953, stripped

source在这种情况下如何调试？

Answer 1

您只能是source脚本,而不是可执行文件.尝试:

while true; do clear; jobs; sleep 2; done
