# Send Bash to your agent
Hand the extracted package to your coding agent with a concrete install brief instead of figuring it out manually.
## Fast path
- Download the package from Yavira.
- Extract it into a folder your agent can access.
- Paste one of the prompts below and point your agent at the extracted folder.
## Suggested prompts
### New install

```text
I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Tell me what you changed and call out any manual steps you could not complete.
```
### Upgrade existing

```text
I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Summarize what changed and any follow-up checks I should run.
```

## Documentation

### Quick Reference

TopicFileArrays and loopsarrays.mdParameter expansionexpansion.mdError handling patternserrors.mdTesting and conditionalstesting.md

### Quoting Traps

Always quote variables—"$var" not $var, spaces break unquoted
"${arr[@]}" preserves elements—${arr[*]} joins into single string
Single quotes are literal—'$var' doesn't expand
Quote command substitution—"$(command)" not $(command)

### Word Splitting and Globbing

Unquoted $var splits on whitespace—file="my file.txt"; cat $file fails
Unquoted * expands to files—quote or escape if literal: "*" or \\*
set -f disables globbing—or quote everything properly

### Test Brackets

[[ ]] preferred over [ ]—no word splitting, supports &&, ||, regex
[[ $var == pattern* ]]—glob patterns without quotes on right side
[[ $var =~ regex ]]—regex match, don't quote the regex
-z is empty, -n is non-empty—[[ -z "$var" ]] tests if empty

### Subshell Traps

Pipes create subshells—cat file | while read; do ((count++)); done—count lost
Use while read < file or process substitution—while read; do ...; done < <(command)
( ) is subshell, { } is same shell—variables in ( ) don't persist

### Exit Handling

set -e exits on error—but not in if, ||, && conditions
set -u errors on undefined vars—catches typos
set -o pipefail—pipeline fails if any command fails, not just last
trap cleanup EXIT—runs on any exit, even errors

### Arrays

Declare: arr=(one two three)—or arr=() then arr+=(item)
Length: ${#arr[@]}—not ${#arr}
All elements: "${arr[@]}"—always quote
Indices: ${!arr[@]}—useful for sparse arrays

### Parameter Expansion

Default value: ${var:-default}—use default if unset/empty
Assign default: ${var:=default}—also assigns to var
Error if unset: ${var:?error message}—exits with message
Substring: ${var:0:5}—first 5 chars
Remove prefix: ${var#pattern}—## for greedy

### Arithmetic

$(( )) for math—result=$((a + b))
(( )) for conditions—if (( count > 5 )); then
No $ needed inside $(( ))—$((count + 1)) not $(($count + 1))

### Common Mistakes

[ $var = "value" ] fails if var empty—use [ "$var" = "value" ] or [[ ]]
if [ -f $file ] with spaces—always quote: if [[ -f "$file" ]]
local in functions—without it, variables are global
read without -r—backslashes interpreted as escapes
echo portability—use printf for reliable formatting
