> you should avoid using [[, preferring to use [ I tend to agree, and have taken this one step further, preferring the "test" command: if test "$a" = "foo" ; then I do this for a few reasons: - "Subsetting" your language can be beneficial: https://wiki.c2.com/?LanguageSubset https://wiki.c2.com/?LanguageSubset - "test" reinforces the notion that this is just the name of a program, not a syntax construct, which encourages using other programs as predicates, e.g. 'if which -s foo'. - "man test" doesn't force you to wade through a 5,000 line man page.
