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 empty … Read more

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 solved grep values and re-arranging the file
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 don’t … Read more
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($0,97)}1’ file file2 1 solved Replace characters 92-97 in position “x” on line
Here is an easy-to-read solution with Bash and grep: #!/bin/bash while read line ; do if FILE=$(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
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 oneliner … Read more
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 river … Read more
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 solved Script to grep on range of start/end text [closed]
