Duplicated Code
Duplicated code can lead to software that is hard to understand and difficult to change. The Don't Repeat Yourself (DRY) principle states:
Every piece of knowledge must have a single, unambiguous, authoritative representation within a system.
When you violate DRY, bugs and maintenance problems are sure to follow. Duplicated code has a tendency to both continue to replicate and also to diverge (leaving bugs as two similar implementations differ in subtle ways).
Tuning
This issue has a mass of 45.
We set useful threshold defaults for the languages we support but you may want to adjust these settings based on your project guidelines.
The threshold configuration represents the minimum mass a code block must have to be analyzed for duplication. The lower the threshold, the more fine-grained the comparison.
If the engine is too easily reporting duplication, try raising the threshold. If you suspect that the engine isn't catching enough duplication, try lowering the threshold. The best setting tends to differ from language to language.

Cognitive Complexity
Cognitive Complexity is a measure of how difficult a unit of code is to intuitively understand. Unlike Cyclomatic Complexity, which determines how difficult your code will be to test, Cognitive Complexity tells you how difficult your code will be to read and comprehend.
A method's cognitive complexity is based on a few simple rules:
- Code is not considered more complex when it uses shorthand that the language provides for collapsing multiple statements into one
- Code is considered more complex for each "break in the linear flow of the code"
- Code is considered more complex when "flow breaking structures are nested"

MD009 - Trailing spaces
Tags: whitespace
Aliases: no-trailing-spaces
Parameters: br_spaces (number; default: 0)
This rule is triggered on any lines that end with whitespace. To fix this, find the line that is triggered and remove any trailing spaces from the end.
The brspaces parameter allows an exception to this rule for a specific amount of trailing spaces used to insert an explicit line break/br element. For example, set brspaces to 2 to allow exactly 2 spaces at the end of a line.
Note: you have to set brspaces to 2 or higher for this exception to take effect - you can't insert a br element with just a single trailing space, so if you set brspaces to 1, the exception will be disabled, just as if it was set to the default of 0.

MD022 - Headers should be surrounded by blank lines
Tags: headers, blank_lines
Aliases: blanks-around-headers
This rule is triggered when headers (any style) are either not preceded or not followed by a blank line:
# Header 1

Some more text
## Header 2
To fix this, ensure that all headers have a blank line both before and after (except where the header is at the beginning or end of the document):
# Header 1
Some text
Some more text
## Header 2
Rationale: Aside from aesthetic reasons, some parsers, including kramdown, will not parse headers that don't have a blank line before, and will parse them as regular text.

Quote this to prevent word splitting
Problematic code:
ls -l $(getfilename)
Correct code:
# getfilename outputs 1 file
ls -l "$(getfilename)"
# getfilename outputs multiple files, linefeed separated
getfilename | while IFS='' read -r line
do
ls -l "$line"
done
Rationale:
When command expansions are unquoted, word splitting and globbing will occur. This often manifests itself by breaking when filenames contain spaces.
Trying to fix it by adding quotes or escapes to the data will not work. Instead, quote the command substitution itself.
If the command substitution outputs multiple pieces of data, use a loop instead.
Exceptions
In rare cases you actually want word splitting, such as in
gcc $(pkg-config --libs openssl) client.c
This is because pkg-config
outputs -lssl -lcrypto
, which you want to break up by spaces into -lssl
and -lcrypto
. An alternative is to put the variables to an array and expand it:
args=( $(pkg-config --libs openssl) )
gcc "${args[@]}" client.c
The power of using an array becomes evident when you want to combine, for example, the command result with user-provided arguments:
compile () {
args=( $(pkg-config --libs openssl) "${@}" )
gcc "${args[@]}" client.c
}
compile -DDEBUG
+ gcc -lssl -lcrypto -DDEBUG client.c

SC2009 Consider using pgrep instead of grepping ps output.
Problematic Code:
ps ax | grep -v grep | grep "$service" > /dev/null
Correct Code:
pgrep -f "$service" > /dev/null
Rationale:
If you are just after a pid from a running program, then pgrep is a much safer alternative. Especially if you are also looking for a pid belonging to a certain user or group. All of the parameters are in one command and it can eliminate multiple greps, cuts, seds, awks, ect.
Exceptions
What if you have the pid and you are looking for the matching program name?
pid=123; ps ax | grep "$pid"
What if you want a range of the ps field, like from the 16th space to the end of the line?
ps ax | grep "$pid" | cut -d" " -f16-
Both are valid cases where SC2009 is not valid.

MD013 - Line length
Tags: line_length
Aliases: line-length Parameters: linelength, codeblocks, tables (number; default 80, boolean; default true)
This rule is triggered when there are lines that are longer than the configured line length (default: 80 characters). To fix this, split the line up into multiple lines.
This rule has an exception where there is no whitespace beyond the configured line length. This allows you to still include items such as long URLs without being forced to break them in the middle.
You also have the option to exclude this rule for code blocks and tables. To
do this, set the code_blocks
and/or tables
parameters to false.
Code blocks are included in this rule by default since it is often a requirement for document readability, and tentatively compatible with code rules. Still, some languages do not lend themselves to short lines.

foo appears unused. Verify it or export it.
Problematic code:
foo=42
echo "$FOO"
Correct code:
foo=42
echo "$foo"
Rationale:
Variables not used for anything are often associated with bugs, so ShellCheck warns about them.
Also note that something like local let foo=42
does not make a let
statement local -- it instead declares an additional local variable named let
.
Exceptions
ShellCheck may not always realize that the variable is in use (especially with indirection), and may not realize you don't care (with throwaway variables or unimplemented features).
For throwaway variables, consider using _
as a dummy:
read _ last _ zip _ _ <<< "$str"
echo "$last, $zip"
or use a directive to disable the warning:
# shellcheck disable=SC2034
read first last email zip lat lng <<< "$str"
echo "$last, $zip"
For indirection, there's not much you can do without rewriting to use arrays or similar:
bar=42 # will always appear unused
foo=bar
echo "${!foo}"
This is expected behavior, and not a bug. There is no good way to statically analyze indirection in shell scripts, just like static C analyzers have a hard time preventing segfaults.
As always, there are ways to [[ignore]] this and other messages if they frequently get in your way.
