Suppose I have the string 1:2:3:4:5
and I want to get its last field (5
in this case). How do I do that using Bash? I tried cut
, but I don't know how to specify the last field with -f
.
You can use string operators:
$ foo=1:2:3:4:5
$ echo ${foo##*:}
5
This trims everything from the front until a ':', greedily.
${foo <-- from variable foo
## <-- greedy front trim
* <-- matches anything
: <-- until the last ':'
}
