sed: Function /jl/s/x//u01/app/oracle/g cannot be parsed.
然后 sed  '/jl/s/x/'${V_L//\//\\\/}'/g' a.txt
ksh: "/jl/s/x/"${V_L//\//\\\/}"/g": 0403-011 The specified substitution is not valid for this command.

s###等价于s///，除了#还可以用其他符号代替。

The syntax of the `s' (as in substitute) command is
`s/REGEXP/REPLACEMENT/FLAGS'.  The `/' characters may be uniformly
replaced by any other single character within any given `s' command.
The `/' character (or whatever other character is used in its stead)
can appear in the REGEXP or REPLACEMENT only if it is preceded by a `\'
character.
