ltrace
intercepts and records dynamic library calls made by a process and signals
TLDR
Trace library calls
$ ltrace [path/to/program]
Count library calls with summary$ ltrace -c [path/to/program]
Trace specific functions$ ltrace -e malloc+free-@libc.so* [path/to/program]
Write trace to file$ ltrace -o [file] [path/to/program]
SYNOPSIS
ltrace [options] [command [args]]
DESCRIPTION
ltrace intercepts and records dynamic library calls made by a process and signals received. It is useful for debugging and understanding how programs interact with shared libraries.
PARAMETERS
-c
Count library calls and print summary-e EXPR
Filter specific library calls-o, --output FILE
Write output to file-p PID
Attach to running process-f
Follow child processes-t
Print timestamps-T
Show time spent in calls-S
Also trace system calls
CAVEATS
May significantly slow down traced programs. Not all library calls may be intercepted on all architectures. Requires debug symbols for detailed output.
