# ltrace
> Display dynamic library calls of a process.
> More information: <https://manned.org/ltrace>.
- Print (trace) library calls of a program binary:
`ltrace ./{{program}}`
- Count library calls. Print a handy summary at the bottom:
`ltrace -c {{path/to/program}}`
- Trace calls to malloc and free, omit those done by libc:
`ltrace -e malloc+free-@libc.so* {{path/to/program}}`
- Write to file instead of terminal:
`ltrace -o {{file}} {{path/to/program}}`
