replace a newline using sed linux bash
# sed is intended to be used on line-based input. Although it can do what you need.
#A better option here is to use the tr command as follows:
tr 'n' ' ' < input_filename
#or remove the newline characters entirely:
tr -d 'n' < input.txt > output.txt
#or if you have the GNU version (with its long options)
tr --delete 'n' < input.txt > output.txtreplace a newline using sed linux bash
#All alternatives, unlike sed will not need to reach the last line to begin the process
#with bash, slow
while read line; do printf "%s" "$line "; done < file
#with perl, sed-like speed
perl -p -e 's/n/ /' file
#with tr, faster than sed, can replace by one character only
tr 'n' ' ' < file
#with paste, tr-like speed, can replace by one character only
paste -s -d ' ' file
#with awk, tr-like speed
awk 1 ORS=' ' file
#Other alternative like "echo $(< file)" is slow, works only on small files and needs to process the whole file to begin the process.Copyright © 2021 Codeinu
