unzip -o {} tells the system to unzip the file placeholder ( {} ). The -o flag overwrites existing files without prompting.
find . -name "*.zip" -exec unzip -o {} \;
If you have enabled globstar in bash, you can avoid find : unzip all files in subfolders linux
#!/usr/bin/env bash set -euo pipefail root="/path/to/root" log="/var/log/unzip-batch.log" find "$root" -type f -iname '*.zip' -print0 | while IFS= read -r -d '' zip; do dir="$(dirname "$zip")" base="$(basename "$zip" .zip)" dest="$dir/$base" mkdir -p "$dest" if unzip -q "$zip" -d "$dest"; then echo "$(date -Iseconds) OK $zip" >> "$log" else echo "$(date -Iseconds) FAIL $zip" >> "$log" fi done
Example zip-slip mitigation (basic):
| Component | Purpose | |-----------|---------| | find | Recursively traverse directory tree | | -name "*.zip" | Match files ending in .zip (case-sensitive; use -iname for case-insensitive) | | -type f | Restrict to regular files (excludes directories named .zip ) | | -execdir | Execute the command the file’s containing directory | | unzip -o | Extract, overwriting existing files without prompting | | {} \; | Placeholder for matched file; terminator for -execdir |
(Adapt as needed; this is more complex and costly.) unzip -o {} tells the system to unzip
This will merge all extracted files into ~/extracted_all , but beware of name collisions.
Conversely, if you only want to extract missing files and skip files that already exist in the target directory, use the -n flag: -name "*
find /path/to/parent -name "*.zip" -type f | while read -r zipfile; do target_dir=$(dirname "$zipfile") unzip -o "$zipfile" -d "$target_dir" done
Suppose you only want to extract .txt or .jpg files from the nested ZIPs. unzip has a built‑in filter:
