LPIC-1 Shells, Scripting and Data Management Practice Question
Exhibit
Refer to the exhibit. $ ls -l /usr/local/bin/myapp -rwxr-xr-x 1 root root 12345 Jan 1 12:00 /usr/local/bin/myapp $ file /usr/local/bin/myapp /usr/local/bin/myapp: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 2.6.32, stripped $ ldd /usr/local/bin/myapp linux-vdso.so.1 (0x00007ffe5a3b0000) libc.so.6 => /lib64/libc.so.6 (0x00007f9a8b200000) /lib64/ld-linux-x86-64.so.2 (0x00007f9a8b600000)
A user reports that running '/usr/local/bin/myapp' from the command line results in 'bash: /usr/local/bin/myapp: No such file or directory'. The exhibit shows the file exists and is a valid executable. What is the most likely cause of the error?
⚠ Common exam trap
It's easy for candidates to confuse the 'No such file or directory' error for the executable itself with a missing library or permission issue, but the error actually refers to the dynamic linker that the executable depends on, not the executable file.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The dynamic linker /lib64/ld-linux-x86-64.so.2 is missing or corrupted.
When a dynamically linked executable exists and is valid but fails with 'No such file or directory', the most common cause is that the dynamic linker (e.g., /lib64/ld-linux-x86-64.so.2) is missing or corrupted. Bash reports this error because the kernel's execve() syscall cannot find the interpreter specified in the ELF's PT_INTERP segment, not because the executable itself is absent. This is a classic symptom distinct from a missing library, which would produce 'error while loading shared libraries'.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The script interpreter specified in the shebang is missing.
Why it's wrong here
It's an ELF binary, not a script.
- ✗
The library libc.so.6 is missing.
Why it's wrong here
ldd shows it is present.
- ✓
The dynamic linker /lib64/ld-linux-x86-64.so.2 is missing or corrupted.
Why this is correct
The binary uses this interpreter; if missing, loading fails.
- ✗
The file does not have execute permission for the user.
Why it's wrong here
The file has execute permission for all.
