Line Editors in Linux, Tips and Tricks

I will log various ways through which tools like sed, cut and tr can be used.
sed 😥
Print specific lines from a file using line numbers.
# print lines 12 to 22
sed -n '12,22p' file.txt
Omit first line of output.
sed -n '1!p'
Omit last line of file.
sed '$d' file.txt
Print everything after a pattern (inclusive).
sed -n '/pattern/,$ p' file.txt
Print everything before a pattern (inclusive).
sed -n '1,/pattern/ p' file.txt
Print everything between two patterns
sed -nE '/^foo/,/^bar/p' file.txt
Avoid printing the searched pattern
sed -n 's/^my_string//p' file.md
Insert contents of file after a certain line
sed '5 r newfile.txt' file.txt
Change line containing regex/pattern match
sed '/MATCH THIS/c\REPLACE WITH THIS' file.txt
tr ➡️
Translate (or convert) all () to [] in a text file.
tr '()' '[]'
Translate all occurrences of multiple spaces with a single space.
tr -s ' '
Remove unwanted characters from string.
# will delete % and ;
echo "1;00%" | tr -d "%;"
cut ✂️
Print every 4th word (or field) from a space separated STDIN.
cut -d' ' -f4
I don't know about you but this is pretty cool.
awk
Don't print first line of file
awk NR\>1 file.txt
