---name: bash-linuxdescription: "Bash/Linux terminal patterns. Critical commands, piping, error handling, scripting. Use when working on macOS or Linux systems."risk: unknownsource: communitydate_added: "2026-02-27"--- # Bash Linux Patterns > Essential patterns for Bash on Linux/macOS. --- ## 1. Operator Syntax ### Chaining Commands | Operator | Meaning | Example ||----------|---------|---------|| `;` | Run sequentially | `cmd1; cmd2` || `&&` | Run if previous succeeded | `npm install && npm run dev` || `\|\|` | Run if previous failed | `npm test \|\| echo "Tests failed"` || `\|` | Pipe output | `ls \| grep ".js"` | --- ## 2. File Operations ### Essential Commands | Task | Command ||------|---------|| List all | `ls -la` || Find files | `find . -name "*.js" -type f` || File content | `cat file.txt` || First N lines | `head -n 20 file.txt` || Last N lines | `tail -n 20 file.txt` || Follow log | `tail -f log.txt` || Search in files | `grep -r "pattern" --include="*.js"` || File size | `du -sh *` || Disk usage | `df -h` | --- ## 3. Process Management | Task | Command ||------|---------|| List processes | `ps aux` || Find by name | `ps aux \| grep node` || Kill by PID | `kill -9 <PID>` || Find port user | `lsof -i :3000` || Kill port | `kill -9 $(lsof -t -i :3000)` || Background | `npm run dev &` || Jobs | `jobs -l` || Bring to front | `fg %1` | --- ## 4. Text Processing ### Core Tools | Tool | Purpose | Example ||------|---------|---------|| `grep` | Search | `grep -rn "TODO" src/` || `sed` | Replace | `sed -i 's/old/new/g' file.txt` || `awk` | Extract columns | `awk '{print $1}' file.txt` || `cut` | Cut fields | `cut -d',' -f1 data.csv` || `sort` | Sort lines | `sort -u file.txt` || `uniq` | Unique lines | `sort file.txt \| uniq -c` || `wc` | Count | `wc -l file.txt` | --- ## 5. Environment Variables | Task | Command ||------|---------|| View all | `env` or `printenv` || View one | `echo $PATH` || Set temporary | `export VAR="value"` || Set in script | `VAR="value" command` || Add to PATH | `export PATH="$PATH:/new/path"` | --- ## 6. Network | Task | Command ||------|---------|| Download | `curl -O https://example.com/file` || API request | `curl -X GET https://api.example.com` || POST JSON | `curl -X POST -H "Content-Type: application/json" -d '{"key":"value"}' URL` || Check port | `nc -zv localhost 3000` || Network info | `ifconfig` or `ip addr` | --- ## 7. Script Template ```bash#!/bin/bashset -euo pipefail  # Exit on error, undefined var, pipe fail # Colors (optional)RED='\033[0;31m'GREEN='\033[0;32m'NC='\033[0m' # Script directorySCRIPT_DIR="$(cd "$(dirname "${BASH_SOURCE[0]}")" && pwd)" # Functionslog_info() { echo -e "${GREEN}[INFO]${NC} $1"; }log_error() { echo -e "${RED}[ERROR]${NC} $1" >&2; } # Mainmain() {    log_info "Starting..."    # Your logic here    log_info "Done!"} main "$@"``` --- ## 8. Common Patterns ### Check if command exists ```bashif command -v node &> /dev/null; then    echo "Node is installed"fi``` ### Default variable value ```bashNAME=${1:-"default_value"}``` ### Read file line by line ```bashwhile IFS= read -r line; do    echo "$line"done < file.txt``` ### Loop over files ```bashfor file in *.js; do    echo "Processing $file"done``` --- ## 9. Differences from PowerShell | Task | PowerShell | Bash ||------|------------|------|| List files | `Get-ChildItem` | `ls -la` || Find files | `Get-ChildItem -Recurse` | `find . -type f` || Environment | `$env:VAR` | `$VAR` || String concat | `"$a$b"` | `"$a$b"` (same) || Null check | `if ($x)` | `if [ -n "$x" ]` || Pipeline | Object-based | Text-based | --- ## 10. Error Handling ### Set options ```bashset -e          # Exit on errorset -u          # Exit on undefined variableset -o pipefail # Exit on pipe failureset -x          # Debug: print commands``` ### Trap for cleanup ```bashcleanup() {    echo "Cleaning up..."    rm -f /tmp/tempfile}trap cleanup EXIT``` --- > **Remember:** Bash is text-based. Use `&&` for success chains, `set -e` for safety, and quote your variables! ## When to UseThis skill is applicable to execute the workflow or actions described in the overview. ## Limitations- Use this skill only when the task clearly matches the scope described above.- Do not treat the output as a substitute for environment-specific validation, testing, or expert review.- Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.
