IP file - 1.txt
$ cat 1.txt
'&1'
'&2'
'&3'
if I want the o/p as
:1
:2
:3
using sed, (or any command for that matter), how do I achieve?
awk '{gsub(/'"^'"'|'"'$"'/,"");gsub(/&/,":")}1' input
:1
:2
:3
Here , awk
's gsub
function is used to replace single quotes to blank and another gsub is used to replace &
to :
. 1
means,print in awk.
You can get your o/p by using below 2 commands.
--> sed -e '/1/b' -e '/2/b' -e '/3/b' -ed 1.txt or --> gsed '/1:2:3/!d' 1.txt
Is this fine ?
sed -e 's/.*[^0-9]\([0-9]\+\)[^0-9]*$/:\1/' 1.txt
:1
:2
:3
$ cat 1.txt
Monday {'&1', 'Morning', 'Breakfast'}
Tuesday {'&2', 'Noon', 'Lunch'}
Wednesday {'&3', 'Evening', 'Supper'}
Thursday {'&4', 'Night', 'Dinner'}
$ sed -E 's/\x27&([0-9]+)\x27/:\1/' 1.txt
Monday {:1, 'Morning', 'Breakfast'}
Tuesday {:2, 'Noon', 'Lunch'}
Wednesday {:3, 'Evening', 'Supper'}
Thursday {:4, 'Night', 'Dinner'}
\\x27&
match single quote and &
(See ASCII set for reference) ([0-9]+)
capture digits for back-referencing \\x27
match single quote :\\1
replace matched pattern with :
and captured digits sed
versions use -r
instead of -E
for extended regex option
