Comparing Strings in the Shell: Pattern Substitution Operator

One problem with using the truncate operator for string matching is case matching.

In the truncate operator example, ${foo%%*ATE} matches SENATE.

DALEK$ if [ '' = "${foo%%*ATE}" ] ; then echo "$foo! $foo!"; fi

It will not match Senate because ate and ATE are different cases.

DALEK$ foo=Senate
DALEK$ if [ '' = "${foo%%*ATE}" ] ; then echo "$foo! $foo!"; fi

Comparing Strings in the Shell: Truncate Operator

While creating materials for my bash class I needed to create some globbing exercises for my students.

It occurred to me that a string operator and a comparison to the null string can be used to check if something is a substring of another value.

Sure, you can use Substring Expansion to see if the substring is at a known location such as "Does the value of $foo start with 'bar'?", but length and location are often unknown.

$ foo=barfood
$ if [ 'bar' = "${foo:0:3}" ]; then echo $foo; fi

LibrePlanet 2018 Experience

PLUG has two topics for August.

Ed Nicholson - Technical Debts and Digital Assets

Exploring the analogy of debt and real world financial obligations, as a context for a software's or system's life cycle. Debt and Software are both fundamentally types of Intangible Assets. This talk is an exploration of how the much older asset class, Debt, may be usefully applied in understanding the relative newcomers, Software and Systems.

der.hans - Introduction to /etc/alternatives
