在bash (多行)中获取两个单词之间的文本

Question

我正在努力解决这个问题。我有一条短信：

Executables:   manatee-curl
Dependencies:  base ==4.*, manatee-core >=0.1.1, dbus-client ==0.3.*,
               stm >=2.1.2.0, containers >=0.3.0.0, gtk >=0.12.0,
               text >=0.7.1.0, mtl >=1.1.0.2, old-time -any,
               old-locale -any, glib >=0.12.0, gio >=0.12.0,
               filepath >=1.1.0.3, utf8-string >=0.3.4, bytestring -any,
               network -any, curl >=1.3.7, directory -any,
               template-haskell -any, derive -any, binary -any,
               regex-tdfa -any, dbus-core -any
Cached:        No

我想把所有这些词放在“属地：”和“缓存”之间。可以将此文本视为变量，例如：

echo $text \ grep /dostuff/

要明确的是，我想得到的输出是：

base ==4.*, manatee-core >=0.1.1, dbus-client ==0.3.*,
stm >=2.1.2.0, containers >=0.3.0.0, gtk >=0.12.0,
text >=0.7.1.0, mtl >=1.1.0.2, old-time -any,
old-locale -any, glib >=0.12.0, gio >=0.12.0,
filepath >=1.1.0.3, utf8-string >=0.3.4, bytestring -any,
network -any, curl >=1.3.7, directory -any,
template-haskell -any, derive -any, binary -any,
regex-tdfa -any, dbus-core -any

谢谢。

您可以使用sed在两个模式之间获取文本：

text=$(sed -n '/^Dependencies:/,/^Cached:/{$d;s/Dependencies: *//;p;}' file)

echo "$text"

base ==4.*, manatee-core >=0.1.1, dbus-client ==0.3.*,
               stm >=2.1.2.0, containers >=0.3.0.0, gtk >=0.12.0,
               text >=0.7.1.0, mtl >=1.1.0.2, old-time -any,
               old-locale -any, glib >=0.12.0, gio >=0.12.0,
               filepath >=1.1.0.3, utf8-string >=0.3.4, bytestring -any,
               network -any, curl >=1.3.7, directory -any,
               template-haskell -any, derive -any, binary -any,
               regex-tdfa -any, dbus-core -any

awk去营救！

$ awk '/^Dependencies:/{$1="";p=1} /^Cached:/{p=0} p{sub(/^ +/,"");print}' file

base ==4.*, manatee-core >=0.1.1, dbus-client ==0.3.*,
stm >=2.1.2.0, containers >=0.3.0.0, gtk >=0.12.0,
text >=0.7.1.0, mtl >=1.1.0.2, old-time -any,
old-locale -any, glib >=0.12.0, gio >=0.12.0,
filepath >=1.1.0.3, utf8-string >=0.3.4, bytestring -any,
network -any, curl >=1.3.7, directory -any,
template-haskell -any, derive -any, binary -any,
regex-tdfa -any, dbus-core -any

您可以像往常一样为一个变量赋值。

$ text=$(awk ...)
