问题 I have a file as below with n number of rows, I want to total it's sum(based on 3rd column) and distribute rows accordingly in 3 different files(based on sum of each) For example- if we sum all the 3rd column values it's total is coming as 516 and if we divide it by 3 it is 172.

问题 I am trying to run the below in jenkins and i get error any suggestions? sh ''' sed -i \':a;N;$!ba;s/\\n/\\|\\#\\|/g\' ${concl} ''' Error - Why isnt the ${concl} being repalced with filename inside the shell script? + sed -i ':a;N;$!ba;s/\n/\|\#\|/g' sed: no input files 回答1: I would suggest running bash command in double quotes and escape $ and \ character.

问题 I'm trying to store a string in a variable, then expand that variable in a sed command. Several of the values I'm going to put in the variable before calling the command will have parentheses (with and without slashes before the left parentheses, but never before the right), new lines and other special characters. Also, the string will have double quotes around it in the file that's being searched, and I'd like to use those to limit only to the string I'm querying. The command needs to be

问题 I was trying to match/output all the text before the first ] appeared: sed -i -r 's/^([^\]]*).*/\1/' "$FILE.tmp" Which surprisingly does not work. However, searching for the other bracket does work: sed -i -r 's/^([^\[]*).*/\1/' "$FILE.tmp" Is this a sed bug or am I doing it wrong? I know I can work around this using .*? which is good enough but this issue had me stumped for long enough that I'd like to know if there is something I missed. (According --version, I am using GNU sed 4.2.2.) 回答1:

问题 I am trying to swap the first line with last line in a text file in unix file has: line1 line2 line3 line4 line5 line6 I want like this: line6 line2 line3 line4 line5 line1 I am using sed -n -e '1 s/^.*$/$p' file . Which is not happening. 回答1: EDIT2: As per Ed sir's comment adding this solution too here which will be more suitable in case 2nd line is empty then also it will work. awk 'NR==1{first=$0;next} NR>2{val=val prev ORS} {prev=$0} END{print prev ORS val first} Input_file EDIT: To

问题 It is simple to extract all ip addresses with grep from a string. string="221.11.165.237xxxx221.11.165.233\n 219.158.9.97ttttt219.158.19.137" echo $string |grep -oP "(\d+\.){3}\d+" 221.11.165.237 221.11.165.233 219.158.9.97 219.158.19.137 The regrex pattern is simple (\d+\.){3}\d+ . Do the same job with sed and awk. For sed: echo $string | sed 's/^\(\(\d\+\.\)\{3\}\d\+\)$/\1/g' 221.11.165.237xxxx221.11.165.233\n 219.158.9.97ttttt219.158.19.137 For awk: echo $string |gawk 'match($0,/(\d+\.){3}

问题 I have lines in a file that look like this: FA General,1234567^^^^^FA Student Letter- General^<<undefined>>^\\path\to\file.RTF I'm trying to use sed to replace the caret characters with commas. If I use: sed 's/\^/,/' file.txt Nothing changes. I've also tried sed 's/\\^/,/' file.txt sed 's/^^/,/' file.txt What am I missing here? 回答1: Do you want to replace all carets? I am sure if you look closely at your result you'll see that the first caret is replaced. So try this: sed -e 's/\^/,/g' file

问题 I would like to search for a pattern in bunch of source files. The pattern should act as a marker. If the pattern is found, I would like to process that line by performing a substitution of another string For example: Private const String myTestString = @"VAL15"; // STRING—REPLACE-VAL## Here, I want to search my source file for pattern STRING—REPLACE-VAL and then replace VAL15 with VAL20 in same. Output: private const String myTestString = @"VAL20"; // STRING—REPLACE-VAL## Tried below command
