[SOLVED] text munging problem

syg00 · 04-14-2023, 05:15 PM

Personally I prefer [^[:space:]] in this context but the effect is likely the same. There is also no requirement for the capture group, & suffices. One-liners are often unnecessarily disparaged.

I tried this and it works.

I tried this and couldn't make it work. Please post working code.

I like one-liners. If concise code is difficult to read it should be commented.

I agree with the people who said to use sed. If you used Python, you'd just do the same regular-expression search-and-replace that you'd do in sed.

Code:

❯ echo "left -21 exMAX_14" | sed -E 's/(\b\w*MAX\w*\b)/\1_33/'
left -21 exMAX_14_33

I tried this and couldn't make it work. With this minor modification it does work.

Code:

sed -E 's/(\b\w*MAX\w*\b)/\1_33/g'

Example with & (reference to all captured)

Code:

sed 's/MAX[[:graph:]]*/&_33/g' $InFile >$OutFile

This solution wins a prize for being concise and readable!
