## `shellcheck` {#tester-shellcheck}
120
+
121
+
Runs files through `shellcheck`, a static analysis tool for shell scripts.
122
+
123
+
:::{.example #ex-shellcheck}
124
+
# Run `testers.shellcheck`
125
+
126
+
A single script
127
+
128
+
```nix
129
+
testers.shellcheck {
130
+
name = "shellcheck";
131
+
src = ./script.sh;
132
+
}
133
+
```
134
+
135
+
Multiple files
136
+
137
+
```nix
138
+
let
139
+
inherit (lib) fileset;
140
+
in
141
+
testers.shellcheck {
142
+
name = "shellcheck";
143
+
src = fileset.toSource {
144
+
root = ./.;
145
+
fileset = fileset.unions [
146
+
./lib.sh
147
+
./nixbsd-activate
148
+
];
149
+
};
150

}

### Inputs {#tester-shellcheck-inputs}
156
+
157
+
[`src` (path or string)]{#tester-shellcheck-param-src}
158
+
159
+
: The path to the shell script(s) to check.
160
+
This can be a single file or a directory containing shell files.
161
+
All files in `src` will be checked, so you may want to provide `fileset`-based source instead of a whole directory.
162
+
163
+
### Return value {#tester-shellcheck-return}
164
+
165
+
A derivation that runs `shellcheck` on the given script(s).
166
+
The build will fail if `shellcheck` finds any issues.
167
+
168
## `testVersion` {#tester-testVersion}
169
170
Checks that the output from running a command contains the specified version string in it as a whole word.
