Hi everyone,
I have a configuration file that has variables and value separate by spaces. I want to take the value (in the second column) of certain matches and inline edit the file, dividing this match by 2. I also would like to preserve spacing and use a ceiling function on the value.
For example, the file:

I know that usually you don't want one-liners/single commands to get too long but it seems like there's occasionally a longish one-liner that would benefit from replacing repetitive elements with a function.
Is it possible to use a short function chop down the length of your command?
For example there's no ceiling or round function ...

Certain languages like awk script allow for conditional assignments. For example, say you had a list file in the format:
<item name, no spaces> <price as float>
e.g.
Grape 4.99
JuicyFruitGum 0.45
Candles 5.99
And you wanted to tax everything over $1... you could use the awk script:
awk '{a=($2>1.00)?$2*1.06:$2; print a}' prices.d...

However, if I only have the 3D, how can I append the \x so printf will print the = and not \x3D.

I am amazed by how Expect (TCL) can automate a lot of things I normally could not do.
I thought I could dig deeper into Expect by reading a book, but before I do that I want to ask if there are other solutions/languages that could do what Expect does?
Eg. I have read that people compare Expect with Awk and also Perl.
Could Awk and Per...
