Any ideas? I am attempting to write a script that uses sed.
If done this way it fails
- rmdec=“sed ‘s/…$//’”
- i1xmr=$(echo “$i1p/$apiresponse*1000” |bc -l |$rmdec)
But if i do it this way it works
- i1xmr=$(echo “$i1p/$apiresponse*1000” |bc -l | sed ‘s/…$//’)
Strings work fine, the problem is the (single) quotes:
~ $ foo="echo 'hello world'" ~ $ for x in $foo; do echo $x; done echo 'hello world' ~ $ $foo 'hello world' ~ $ eval "$foo" hello world
The splitting is by whitespace, so the single quotes remain in the arguments. Using eval (and double quotes to preven splitting), it gets processed correctly. That said, don’t use eval; use functions or aliases instead.
