I'd like to change the following patterns:
getFoo_Bar to:
getFoo_bar (note the lower b)
Knowing neither foo nor bar, what is the replacement pattern?
I started writing
sed 's/\(get[A-Z][A-Za-z0-9]*_\)\([A-Z]\)/\1 but I'm stuck: I want to write "\2 lower case", how do I do that?
Maybe sed is not adapted?

The `tr` command can be used in the following way to convert any string from uppercase to lowercase. You can use `tr` command in the following way also to convert any string from lowercase to uppercase.
Just add the line number before: sed '<line number>s/<search pattern>/<replacement string>/ . Note I use . bak after the -i flag. This will perform the change in file itself but also will create a file.
To use a keyboard shortcut to change between lowercase, UPPERCASE, and Capitalize Each Word, select the text and press SHIFT + F3 until the case you want is applied.
To change getFoo_Bar to getFoo_bar using sed :
echo "getFoo_Bar" | sed 's/^\(.\{7\}\)\(.\)\(.*\)$/\1\l\2\3/' The upper and lowercase letters are handled by :
\U Makes all text to the right uppercase.\u makes only the first character to the right uppercase.\L Makes all text to the right lowercase.\l Makes only the first character to the right lower case. (Note its a lowercase letter L)The example is just one method for pattern matching, just based on modifying a single chunk of text. Using the example, getFoo_BAr transforms to getFoo_bAr, note the A was not altered.

s/\(get[A-Z][A-Za-z0-9]*_\)\([A-Z]\)/\1\L\2/g Test:
$ echo 'getFoo_Bar' | sed -e 's/\(get[A-Z][A-Za-z0-9]*_\)\([A-Z]\)/\1\L\2/g' getFoo_bar If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
