Linux 要复制（scp）和重命名的Shell脚本

我的服务器中有一个文件夹，其中包含一些PDF文件。我的问题是，我必须复制到其他服务器并重命名它

名称格式类似于“yymmdd\u hhmmss\u FileNo\u PdfNo.pdf”

复制这些文件时，我想重命名每个文件。 名称格式如下“FileNo_PdfNo_yymddhhmmss.pdf”

我想为此编写一个shell脚本（bash）。请给我一些与此相关的想法或示例脚本。

使用GNU tar：

tar -cf - *.pdf | ssh user@server "tar -xvf - --transform='s/\(.\{6\}\)_\(.\{6\}\)_\(...\)_\(.\{3,\}\)\.pdf/\3_\4_\1\2.pdf/' --show-transformed-names"

如果要更改目标目录，请使用tar的选项

-C

请参阅：

稍作调整，这应该适合您。我把解释/评论放在脚本中。您可能不需要循环就可以做到这一点，但同时使用scp传输和重命名多个文件会变得很棘手。如果您在本地重命名它们，然后转移它们，那么就很容易进行单个scp调用。你也可以把它浓缩成一行；但我认为这种方法可能更具解释性，更容易修改

#!/bin/bash - 

# associative array to hold new file names
declare -A new;

# local and remote paths terminated with / for laziness
local_path="/lcl/path/to/pdfs/"
remote_path="/remote/path/to/pdfs/"

# user@machine for remote ssh connection
user_mach="username@machinename"

# error accumulator
local lcl_err=0

# Collect list of files to send - you may want this to be
# more discriminating
orig=`find "$local_path" -name "*.pdf" -exec basename {} \;`

# Iterate through the file list
for i in "${orig[@]}"; do
  # sed replacement to rename them appropriately, stored in
  # associative array new
  new["$i"]="`echo $i | sed -ne 's/^\([0-9]\{6,\}\)_\([0-9]\{6,\}\)_\([0-9]\{3,\}\)_\(.*\)\.pdf$/\3_\4_\1\2\.pdf/p'`"

  # if file was renamed (passed regex filter) then scp it to remote host,
  # saving it remotely with new name
  if [ ${new["$i"]} ]; then
    scp "${local_path}$i" "${user_mach}:${remote_path}${new["$i"]}"
    # don't roll over the return value (256 == 0 in 8 bit return value)
    [[ "$lcl_err" -lt "255" ]] && ((lcl_err+=$?))
  else
    echo "Skipping file $i"
  fi
done
exit "$lcl_err"

scp源名称user@remote_host：dest_name

或者如果需要，可以

scp

整个目录，然后

sshuser@remote_hostprename…

command添加到目前为止所做的事情总是很好的。请参阅@anishsane，这并不能真正解决他的问题，因为他想增加文件名开头的数字，所以他需要首先检查现有文件，以获得当前的数字。^^从问题中的代码段看，情况并非如此；或者至少还不清楚。我解释为文件名中的部分（用下划线分隔）需要重新排列。

tar -cf - *.pdf | ssh user@server "tar -xvf - --transform='s/\(.\{6\}\)_\(.\{6\}\)_\(...\)_\(.\{3,\}\)\.pdf/\3_\4_\1\2.pdf/' --show-transformed-names"

#!/bin/bash - 

# associative array to hold new file names
declare -A new;

# local and remote paths terminated with / for laziness
local_path="/lcl/path/to/pdfs/"
remote_path="/remote/path/to/pdfs/"

# user@machine for remote ssh connection
user_mach="username@machinename"

# error accumulator
local lcl_err=0

# Collect list of files to send - you may want this to be
# more discriminating
orig=`find "$local_path" -name "*.pdf" -exec basename {} \;`

# Iterate through the file list
for i in "${orig[@]}"; do
  # sed replacement to rename them appropriately, stored in
  # associative array new
  new["$i"]="`echo $i | sed -ne 's/^\([0-9]\{6,\}\)_\([0-9]\{6,\}\)_\([0-9]\{3,\}\)_\(.*\)\.pdf$/\3_\4_\1\2\.pdf/p'`"

  # if file was renamed (passed regex filter) then scp it to remote host,
  # saving it remotely with new name
  if [ ${new["$i"]} ]; then
    scp "${local_path}$i" "${user_mach}:${remote_path}${new["$i"]}"
    # don't roll over the return value (256 == 0 in 8 bit return value)
    [[ "$lcl_err" -lt "255" ]] && ((lcl_err+=$?))
  else
    echo "Skipping file $i"
  fi
done
exit "$lcl_err"
