Zero-dependency strace implementation based on lizrice/strace-from-scratch.
Arranged to be modifiable using different Interceptors. The default simply prints system calls:
docker run --rm strace echo -n hi
Run [echo -n hi]
arch_prctl
set_tid_address
brk
brk
mmap(94127144218624, 4096, 0, 50, -1, 0)
mprotect
mprotect
getuid() = 0
write(1, "\"hi\"", 2) hi= 2
exit_group
Another interceptor can be enabled with env variables:
FILE=file.zip URL=https://i.ting.st/pg2701.epub ./main unzip -l file.zip
...
lseek(3<file.zip>, 628018, SEEK_SET) = 628018
read(3<file.zip>, 140725387582132, 4)
> GET https://i.ting.st/pg2701.epub
