Joining lines of text on Linux


There are number of ways to sign up with several lines of text and change delimiters if needed. This article reveals 2 of the simpler methods to do this and discusses the commands.Using the tr command The tr command

is rather flexible. It’s utilized to make lots of kinds of changes to text files, but it can likewise flatten multiple lines into one by replacing newline characters with blanks. It does, however, get rid of the last newline as well. Keep in mind the $ timely at the end of the 2nd line. That’s a hint!

$ tr ‘ n”’ < testfile This is a file that I can utilize for screening. $ $ tr ' n''' < testfile > newfile

To repair this problem, you can include a newline to the end of the file with an echo command like this:

$ echo “” >> newfile $ od -bc newfile 0000000 124 150 151 163 040 151 163 040 141 040 146 151 154 145 040 164 T h i s i s a f i l e t 0000020 150 141 164 040 111 040 143 141 156 040 165 163 145 040 146 157 h a t I c a n u s e f o 0000040 162 040 164 145 163 164 151 156 147 056 040 012 r t e s t i n g. n testfile2 The-s(use a single file )and -d( include a delimiter between each of the processed lines) in the command shown above will ensure that the signed up with lines are all separated by blanks. You can,

nevertheless, utilize whatever delimiter

is best for the job. If you include numerous file names with the paste command, each file will be developed into a single line in the output.$paste-sd” testfile testfile2 This is a file that I can use for screening. This is a 2nd file. To conserve the outcome,

reroute the output to a third file. $paste- sd’ ‘testfile testfile2 > newfile$cat newfile This is a file that I can utilize for screening. This is a 2nd file. To turn only the first three lines of a file into a single line, include a head command like this.$ head -3 testfile3 |paste -sd” This is a file that I can If you want to turn every successive group of five lines in a file into a separate line, you have to work a little harder. This script signs up with five lines at a time into one by putting those lines to a different file and after that flattening it
