regexp inverse selection
selecting all rows not matchng (viasual studio code tested)
class="ms-Checkbox-text text-284">01/10/2020</span>
^((?!.*text-284.*\<\/span\>).)*$
regexp no-greedy / lazy (stops on first occurence)
You need to make your regular expression non-greedy, because by default, "(.*)" will match all of "file path/level1/level2" xxx some="xxx".
Instead you can make your dot-star non-greedy, which will make it match as few characters as possible:
/location="(.*?)"/
Adding a ? on a quantifier (?, * or +) makes it non-greedy.
Finding files in tar archives / extract selected file
tar -ft large_file.tar.gz | grep "the-filename-you-want"
Output:
"full-path/to-the-file/in-the-archive/the-filename-you-want"
tar -xf large_file.tar.gz "full-path/to-the-file/in-the-archive/the-filename-you-want"

bash: env variable reset when execute sudo cmd
when execute commands with sudo a new bash envoirment is loaded:
if you try:
sudo env |grep -i proxy
you will get an empty line.
adding this file
/etc/sudoers.d/proxy
containing :
Defaults env_reset
Defaults env_keep += "HTTP_PROXY"
Defaults env_keep += "HTTPS_PROXY"
Defaults env_keep += "http_proxy"
Defaults env_keep += "https_proxy"
now with:
sudo env |grep -i proxy
you'll have this output:
http_proxy=http://192.168.2.3:8080/
https_proxy=http://192.168.2.3:8080/
HTTPS_PROXY=http://192.168.2.3:8080/
HTTP_PROXY=http://192.168.2.3:8080/
so the env variables have passed to the sudo env

Remove or replace newlines using sed,awk,tr - BASH
http://unstableme.blogspot.com/2008/05/remove-or-replace-newlines-using.html
$ cat week.txt
Su
Mo
Tu
We
Th
Fr
Sa
Output Required:
- a) Remove the newlines. i.e. required output:
SuMoTuWeThFrSa
- b) Replace the newlines with "|", i.e.
Su|Mo|Tu|We|Th|Fr|Sa
Remove/Replace newlines with sed
a)
$ sed -e :a -e '$!N;s/\n//;ta' week.txt
SuMoTuWeThFrSa
b)
$ sed -e :a -e '$!N;s/\n/|/;ta' week.txt
Su|Mo|Tu|We|Th|Fr|Sa
One more way of doing. But not suitable for files with large number of records, as you see the number of N's is just 1 less than number of lines in the file.
a)
$ sed 'N;N;N;N;N;N;s/\n//g' week.txt
SuMoTuWeThFrSa
b)
$ sed 'N;N;N;N;N;N;s/\n/|/g' week.txt
Su|Mo|Tu|We|Th|Fr|Sa
Remove/Replace newlines with awk
a)
$ awk '{printf "%s",$0} END {print ""}' week.txt
SuMoTuWeThFrSa
b)
$ awk '{printf "%s|",$0} END {print ""}' week.txt
Su|Mo|Tu|We|Th|Fr|Sa|
So we need to remove the last "|" in the above output.
$ awk '{printf "%s|",$0} END {print ""}' week.txt | awk '{sub(/\|$/,"");print}'
Su|Mo|Tu|We|Th|Fr|Sa
Remove/Replace newlines with tr
a)
$ tr -d '\n' < week.txt
SuMoTuWeThFrSa
b)
$ tr '\n' '|' < week.txt
Su|Mo|Tu|We|Th|Fr|Sa|
Similarly we need to remove the last "|" from the above output:
$ tr '\n' '|' < week.txt | sed 's/|$//'
Su|Mo|Tu|We|Th|Fr|Sa
