Find out how to work with substrings on Linux



$ echo "Give attention to Peace on Earth" | minimize -d' ' -f3,5
Peace Earth
$ echo "one two three 4 5 6" | minimize -d' ' -f1-3,6
one two three 6

To make use of an alternate delimiter (on this case, a colon), use a command like this:

$ minimize -d':' -f1-3,5,6 /and so on/passwd | tail -n 5
justme:x:1004:JustMe:/dwelling/justme
lola:x:1006::/dwelling/lola
dumdum:x:1007::/dwelling/dumdum

With awk, you should use multiple delimiter. Within the following instance, two delimiters are specified, so the awk command accepts both a colon or a clean to separate fields. The primary two traces show the file, and the final two traces present the command and outcome.

$ cat file
Monday:1 Tuesday:2 Wednesday:3 Thursday:4 Friday:5
$ awk -F'[: ]' '{OFS=" ";print $1,$3,$4}' file
Monday Tuesday 2

Deciding on substrings

To pick out an arbitrary sequence or characters from a string, you should use an awk command just like the one beneath during which the $0 represents the complete phrase, 10 represents the primary character place to be grabbed and 5 is the size of the string to be displayed.

$ echo "Give attention to Peace" | awk '{print substr($0,10,5)}'
Peace

To do the identical type of factor with the minimize command, you’d use a command like this during which the 13th via 22nd characters are extracted from the phrase and displayed.

$ echo "Linux is a powerful OS" | minimize -c 13-22
spectacular

On this subsequent command, the minimize command shows the 7th-12th characters from the traces in a file. The head command merely limits the show to the primary 4 traces of output.

$ minimize -c 7-12 sayings | head -4
with 3
and ov
nd be
and be

Utilizing grep

You need to use the grep command to pick out a number of phrases from a file. On this instance, solely the chosen phrases are displayed, not the complete traces. It is because the -o (show solely the matched objects) possibility is getting used.

I received drained – Scott Hanselman’s Weblog



I got tired - photo by Elisa VenturI’ve been running a blog right here for the final 20 years. Each Tuesday and Thursday, fairly constantly, for 20 years. However final yr, with out planning it, I received drained and stopped. Undecided why. It did not correspond with any life occasions. Nothing fascinating or notable occurred. I simply stopped.

I did discover pleasure on TikTok and amassed a small group of like-minded followers there. I take pleasure in my YouTube as effectively, and my weekly podcast goes robust with almost 900 (!) episodes of interviews with cool individuals. I’ve additionally just lately began posting on Mastodon (a fediverse (federated universe)) Twitter various that makes use of the ActivityPub net customary. I see that Mark Downie has been ActivityPub as effectively for DasBlog (the weblog engine that powers this weblog) so I have to spend someday with Mark quickly.

Being constant is a tough factor, and I feel I did a very good job. I gave many talks over a few years about Private Productiveness however I at all times talked about doing what “feeds your spirit.” For a minute right here the weblog took a backseat, and that is OK. I stuffed that (spare) time with household time, private tasks, writing extra code, 3d printing, video games, taekwondo, and a ton of different issues.

Going ahead I’ll proceed to put in writing and share throughout numerous platforms, however it is going to proceed to begin right here as it is tremendous vital to Personal Your Phrases. Preserve taking snapshots and backups of your keystrokes as you by no means know when your chosen platform may change or go away fully.

I am nonetheless right here. I hope you’re too! I’ll see you quickly.
