[ad_1] Use this: grep -A 1 -B 1 ‘Server sent’ file.txt | sed ‘/^–$/d’ (OR) grep -C 1 ‘Server sent’ file.txt | sed ‘/^–$/d’ 0 [ad_2] solved Print every 3 strings who are start from special symbols
[ad_1] this can be accomplished in a single awk call. associate numbers with champions in an array and use it for replacing numbers in second file. awk ‘BEGIN{FS=OFS=”,”} NR==FNR{a[$1]=$2;next} {$1=a[$1];$2=a[$2]} 1’ champions.csv top.csv Olaf,Annie,3 Galio,Annie,5 Twisted Fate,Annie,6 Xin Zhao,Annie,1 Urgot,Annie,10 LeBlanc,Annie,9 Vladimir,Annie,11 Kayle,Twisted Fate,12 LeBlanc,Xin Zhao,2 Galio,Galio,6 in case there should be some numbers in … Read more
[ad_1] A very quick way is using awk awk ‘BEGIN{RS=””;ORS=”\n\n”}1’ /path/to/your/file > /path/to/new/file How does this work: awk knowns the concept records (which is by default lines) and you can define a record by its record separator RS. If you set the value of RS to an empty string, it will match any multitude of … Read more
[ad_1] grep -oP ‘^server\s\K[^ ]+|^[^#]\s+\d+:\K[^:]+’ inputfile pool0 server1 server2 pool1 server3 server4 4 [ad_2] solved Extract specific string between two strings and list the required content
[ad_1] Try this awk: awk -F'”‘ ‘NR%2{p1=$4;next} {print p1 “https://stackoverflow.com/” $4}’ Test: $ awk -F'”‘ ‘NR%2{p1=$4;next} {print p1 “https://stackoverflow.com/” $4}’ file abc/123abc bac/bac123 cde/cd123 b4u/b4u234 2 [ad_2] solved grep values and re-arranging the file
[ad_1] Running sed -i on the same file multiple times is a horrible antipattern. Just do all the substitutions in the same sed script. You need to escape many more metacharacters than you currently do. See Escape a string for a sed replace pattern for some details. Probably that’s the reason many of your substitutions … Read more
[ad_1] this one-liner should work: awk ‘NR==FNR{a[$1]=substr($0,92,5);next}($1 in a) {$0=substr($0,1,92) a[$1] substr($0,97)}1’ file file2 1 [ad_2] solved Replace characters 92-97 in position “x” on line
[ad_1] Here is an easy-to-read solution with Bash and grep: #!/bin/bash while read line ; do if FILE=$(grep -P -o ‘[a-z]*\.txt(?= – Starting)’ <<< “$line”); then F=”$FILE” fi if ! grep ‘\*\*\*\*’ <<< “$line” ; then echo “$line” >> “$F” fi done It gives the following result $ cat file.txt ****************** abc.txt – Starting point … Read more
[ad_1] the awk line should work for u: awk ‘FNR==NR{if(NR%2)i=$0;else a[i]=$0;next;}{if($0 in a){print; print a[$0]}else print}’ file2 file1 EDIT here I see no EXTRA lines. see the test. (maybe your example data format is not same as your real data.). however I have shown the way, how to do it. you can change the awk … Read more
[ad_1] Use Perl. Read the CSV file into a hash, build a regular expression from the hash keys, and do a global subtitution on the text using the hash to translate. It looks like this use strict; use warnings; use 5.010; use autodie; my $str = <<‘__END_TEXT__’; The ripple-necked bird sang melodies by the curling … Read more
[ad_1] Since you didn’t provide any details, here is the boiler plate. $ sed -n ‘/start/,/end/p’ file > outputfile or $ awk ‘/start/,/end/’ file > outputfile 3 [ad_2] solved Script to grep on range of start/end text [closed]
