Bashism: Convert the case of a variable

Posted on June 24, 2015 by richard

Following on with more Bash version 4 Shell coding notes, here’s a way (as always with Bash, there’s so many ways to do anything) to ensure a variable is all lowercase characters (or all uppercase):

a=Hello
echo ${a,,}
hello

You can convert to all uppercase characters with echo ${^^}

FYI,
Richard.

Use sed to delete lines between text phrases

Posted on June 19, 2015 by richard

How to remove lines from stdin between and including the 2 lines as fields in a sed expression:

sed "/textline1/,/textline2/d"

This will delete from the input all lines between a line containing the text ‘textline1’ and ‘textline2’.

If you have a / char in either textline entry then you should replace it with the two characters inside the quotes of: ‘\/’
Being “backslash forwardslash” <- with no space between the characters. FYI, Richard.
