Script with readline gives 2 different answers same variable

I'm using the newer command, mapfile, but the principle is the same (see my thread about "lost command line options" or something of that sort).

The script:

Code:

#!/bin/bash

mapfile -t lalaland <alleylocate
file0=${lalaland[0]}
echo $file0
city=${lalaland[1]}
echo $city
sprov=$(echo ${lalaland=[2]})
echo "State is $sprov"

echo ${lalaland[2]}
exit 1
country=${lalaland[3]}
echo $country
ccode=${lalaland[4]}
echo $ccode
exiftool -fast5 -overwrite_original_in_place -P -q -City="$city" -State="$sprov" -Country="$country" -CountryCode="$ccode" "$file0"

exit 0

When run on the attached text file, sprov and lalaland[3] give different answers. The first consistently returns the file name [array item 0] while echoing lalaland3 returns the proper array item (California, in this case).

But it's the 0 line (filename) that's written as "State" by exiftool, and of course I don't want or need that. Am I missing something? Is something out of order?

PS:The name of the attached file was changed to comply with LQ's file validity requirements. When I run the script I use the same text file without the DOS extension, as it appears in the script

Ok, perhaps I don't understand this, but:

(i) In your description, surely you mean lalaland[2] (the state), not lalaland[3] (the country).

(ii) What is that second '=' sign doing in sprov=$(echo ${lalaland=[2]})?

(iii) Why are you assigning sprov anyway? Why aren't you just using state=${lalaland[2]} like the other array elements?

first mention is this

Code:

sprov=$(echo ${lalaland=[2]})

= <----- not suppose to be there

yeapers looks like the above got'er figured out. I was just reading yours. At first. That MAPFILE got my attention.

script

Code:

#!/bin/bash

mapfile -t lalaland <alleylocate
file0=${lalaland[0]}
echo $file0
city=${lalaland[1]}
echo $city
sprov=${lalaland[2]}
echo "State is $sprov"

echo ${lalaland[2]}
exit 1
country=${lalaland[3]}
echo $country
ccode=${lalaland[4]}
echo $ccode
exiftool -fast5 -overwrite_original_in_place -P -q -City="$city" -State="$sprov" -Country="$country" -CountryCode="$ccode" "$file0"

exit 0

Code:

State is California

Which is good, because it gives me something besides the ordinary "Location/Sub-location" fields to which I can add location information. Ordinarily I use those for places like "Beach" or "Home," "Sidewalk or "Driveway."

Thanks again for all the help.
