此代码从目录中获取所有 .stm 文件，并在执行此代码后保存在文件中。

cat db/some_path/stm/*.stm | sort -k1,1 -k2,2 -k4,4n | \
      sed -e 's:<F0_M>:<o,f0,male>:' \
          -e 's:<F0_F>:<o,f0,female>:' \
          -e 's:([0-9])::g' \
          -e 's:<sil>::g' \
          -e 's:([^ ]*)$::' | \
      awk '{ $2 = "A"; print $0; }'
  } | local/join_suffix.py > data/dev.orig/stm

样本输出

我不明白使用 sed -e 如何格式化它。

我对 awk '{ $2 = "A"; print $0; }'每一行的这一行含义的理解取第二个单词并检查它是否等于 A 然后打印第一个单词，但是这些-e 's:<sil>::g'含义是什么？
