以下應工作(注意,在某些系統上,你可能需要刪除所有評論):
sed '1 { # if this is the first line
h # copy to hold space
d # delete pattern space and return to start
}
/^}},$/ { # if this line matches regex /^}},$/
x # exchange pattern and hold space
b # print pattern space and return to start
}
H # append line to hold space
$ { # if this is the last line
x # exchange pattern and hold space
s/^}},/}}/ # replace "}}," at start of pattern space with "}}"
b # print pattern space and return to start
}
d # delete pattern space and return to start'
還是緊湊型:
sed '1{h;d};/^}},$/{x;b};H;${x;s/^}},/}}/;b};d'
例子:
$ echo 'parallel (
{
ignore(FAILURE) {
build("Build2Test", BUILDFILE: "", WARFILE: "http://maven.example.com/130602.0.war", STUDY: "UK", BUG: "33323")
}},
)' | sed '1{h;d};/^}},$/{x;b};H;${x;s/^}},/}}/;b};d'
parallel (
{
ignore(FAILURE) {
build("Build2Test", BUILDFILE: "", WARFILE: "http://maven.example.com/130602.0.war", STUDY: "UK", BUG: "33323")
}}
)
