Question

这是我的部分数据，我需要从行中删除换行符，不包括那些以与格式 |HH:MM:SS.

匹配的序列结尾的行

这是前两条记录。第一条记录以 "Reset system" 开头，第二条记录以 "Collaborator informs".

开头

Reset system password SISMED WE|Collaborator requests password reset of SISMED WEB system.

我需要输出类似下面的东西

有人可以帮我使用 UNIX 命令吗？

谢谢。

在原生 bash 中，旨在提高可读性而非简洁性：

#!/usr/bin/env bash

# if we were passed a filename as an argument, read from that file
# otherwise, this script reads from stdin
[[  ]] && exec <""

# ERE-syntax regex matching end-of-record marker
end_of_record_re='[|][[:digit:]]{2}:[[:digit:]]{2}:[[:digit:]]{2}[[:space:]]*$'

buffer=''                       # start out with an empty buffer
while IFS= read -r line; do     # while we can, read a line.
  if ! [[ $line =~ $end_of_record_re ]]; then # unless it has an end marker...
    buffer+=" $line"                          # ...add to our buffer, preceded by a space
  else                                 # if the line has an end marker...
    printf '%s\n' "${buffer# }${line}" # ...print buffer except for first space
    buffer=                            # ...and reset the buffer to be empty
  fi
done

# finally, if we have trailing content, print it out.
[[ $buffer ]] && printf '%s\n' "${buffer# }"

合并行直到看到记录结束标记

merge lines until end-of-record marker is seen

shell

newline
