Nov 18, 2021 · Consider this program: awk '{n=index($0,"BBBB"); print substr($0,n+4)}' input.txt This will locate the first occurence of the substring BBBB in the current line (denoted by $0) and store the position in n. It will then print the part of the line starting at this position plus 4 (to remove the initial 4 B s) up to the end of the line.

Nov 9, 2022 · Using Miller (mlr) to perform a relational JOIN operation on the named fields that the two files have in common: $ mlr --csv join -j AAAA,BBBB,CCCC,DDDD,EEEE,FFFF,GGGG,HHHH -f file1.csv file2.csv AAAA,BBBB,CCCC,DDDD,EEEE,FFFF,GGGG,HHHH,IIII a,b,c,d,e,f,g,h,i …

> bbbb Thus in your first example your parameter was "a/b" and you told bash to replace the first occurence of "b" in "a/b" (the value of var) with the string "c/d" (which results in "a/c/d").

Apr 11, 2018 · Hey Michael, I totally get this. My work uses a highly customized RHEL6.x / 7.x Image. I've been running across hosts with the IPv6 address stated in both ways above. I've never messed with IPv6 on Windows or Linux, so this is a bit new to me. I guess it would be correct to assume that; gateway_ip:last_hextet of the IPv6 address goes here (2001:db8:2::1:1000). This …

For example: aaaa bbbb cccc dddd eeee ffff The log files can look like this: asd dfg aaaa aaaa sa sdf dddd dddd dddd dddd ghj bbbb cccc cccc cccc fgg fgh hjk The first (and perhaps most obvious approach) is to use grep, sort and uniq in the following way: grep -f patterns.in logfile.txt | sort | uniq -c which gives the following result: 2 aaaa ...

I only want it to match ./aaaa/bbbb/cccc/ but I can't figure out how to do it. I want to specifically match/find all occurrences of "everything before a forward slash up to and including the slash" as I want to use sed to substitute the matches like in the below sed command but not losing the file size bit at the start.

You can do: grep -B 1 '&$' your_file This will look for lines ending in &, remove $ to match lines with & anywhere in them. The -B switch tells grep to output "context" lines that come before the lines that match. In this case, since you want one line of context, you need -B 1.
