sed命令中的错误

Question

input:

43572154    ROR2
43439911    LOC785925
42737842    LOC785930

expected output

'43572154':'ROR2'
'43439911':'LOC785925'
'42737842':'LOC785930'

Commands used

sed s/\n/\'\,\n\'/ input #substitute newline with ',\n'
sed s/ /\'\:\'/ input  #substitute <space> with ':'

But there seems to be no effect on the input. Can anyone please point out my error? Thnx

Answer 1

Why do you try to replace newlines? Try this instead:

sed "s/\([^ ]\+\) \+\(.*\)/'\1':'\2'/" input

EDIT -- or with extended regular expressions ( -r ):

sed -r "s/([^ ]+) +(.*)/'\1':'\2'/" input

Answer 2

这是基于注释的awk解决方案：

awk "{print \"'\" \$1 \"':'\" \$2 \"'\"}" input
