求教： perl 調(diào)用 unix shell 變量 值

ace_fei

類似問(wèn)題太多了，無(wú)非之前是問(wèn)的awk，sed之類
都可以用雙引號(hào)里面套個(gè)單引號(hào)。
如果字符串中含有空格的話，就再套一雙引號(hào)。
#! /bin/bash
a="test_test"
perl -e 'print "'$a'" '
echo
b="test test"
perl -e 'print "'"$b"'" '
echo
c="test"
awk 'BEGIN{print "'$c'"}'

Unix1998

#! /bin/bash
a="test_test"
perl -e 'print "'$a'" '
echo
b="test test"
perl -e 'print "'"$b"'" '


it doesn't work in Solaris , may work in Linux ? who can try it in Linux ?

Regards

Unix1998

#! /bin/bash
a="test_test"
perl -e 'print "'$a'" '
echo
b="test test"
perl -e 'print "'"$b"'" '
echo
c="test"
awk 'BEGIN{print "'$c'"}'


Linux  以上 代碼 可以 ， solaris還是 不行

# there is no issue on Solaris 10 and please use %ENV in Perl to use environment variable easily

$ cat t.sh
#! /bin/bash
a="test_test"
b="test test"
perl -e 'print "sh:'$a'\n" '
perl -e 'print "sh:'"$b"'\n" '
export b
perl -e 'print "env:$ENV\n"'

$ bash t.sh
sh:test_test
sh:test test
env:test test
