• SC1090: Can't follow non-constant source. Use a directive to specify location.
• SC2013: To read lines rather than words, pipe/redirect to a 'while read' loop.
• SC2015: Note that A && B || C is not if-then-else. C may run when A is true.
• SC2044: For loops over find output are fragile. Use find -exec or a while read loop.
• SC2048: Use "$@" (with quotes) to prevent whitespace problems.
• SC2174: When used with -p, -m only applies to the deepest directory.
• SC2162: read without -r will mangle backslashes.
• SC2197: fgrep is non-standard and deprecated. Use grep -F instead.
• SC2016: Expressions don't expand in single quotes, use double quotes for that.
• SC2181: Check exit code directly with e.g. 'if mycmd;', not indirectly with $?.
• SC2046: Quote this to prevent word splitting.
• SC2154: ret is referenced but not assigned.
• SC2155: Declare and assign separately to avoid masking return values.
• SC2166: Prefer [ p ] || [ q ] as [ p -o q ] is not well defined.
• SC2034: appears unused. Verify it or export it.
• SC2128: Expanding an array without an index only gives the first element.
