linux - grep two strings from a file and write into a txt
Answer
Answer
Could you please help me how to grep two strings (or the whole lines) from one file and write them on the same line in output file?
grep -e "string1 string2" inputfile > output.txt doesn't work
for one string it works:
grep -e "string1" inputfile > output.txt
thx!
Answer
Change your grep command like below,
grep -o 'string1\|string2' file | paste - - > out.txt
This writes string1 string2
in a single line on out.txt
