Re^3: How to include a doublequoted string into a backticked expression?

I can't either, because I neither know where your subroutine is called, what the parameters are, especially of $lemma and what the contents of /home/lexicon are, and what the expected output is. Possibly the reply by the good Anonymous Monk is right on, as whatever shell you call will also interpret the command line and interpolate things, a second time. But it's hard to tell, as my array of crystal balls is currently busy divining the lottery numbers for next weekend.

Fair enough, Corion ... I have verified the correct value for `$lemma` by printing it in the subroutine, so I think it should be OK. The file `lexicon` contains many - i.e.: MANY - entries of the format `^\w+\:=($attribute:$value,)+$attribute:$value;` where `$attribute` and `$value` are lexical attributes of a given lemma (essentially a 'word' ... whatever that exactly may be). As I mentioned in my post, the matching works fine when the entire `egrep ...` command is executed from the shell so I think the problem does not originate from difficulties to match the regex. Of course, what is being matched may of course differ between the two invocations based on potentially different results of string interpolation ...	[reply] [d/l] [select]

Well, as you still keep the value of `$lemma` hidden, most likely because the lives of uncounted children depend on it, I can't help you much further. You can help us to help you by providing a self-contained script that reproduces the problem, for example by including relevant parts of the lexicon data in a DATA section.	[reply] [d/l]

A typical line from lexicon: `_DATA_ tragen:=[base:tragen,cat:VVINF,stress:none,perfect:haben,sem_val:ag_th +,valence:a,avz:allowed,extravalence:pdcis,extraobjp:zu]; _END_` [download] A typical lemma value: `$lemma = "tragen";`	[reply] [d/l] [select]
