csh 脚本中出现奇怪的非法变量名错误

我的 csh 脚本出现了一个特殊问题，该问题仅出现在我的 Lenovo Z500 笔记本电脑中。我在其他 3 台具有类似操作系统（Kubuntu 14.04 x64）的计算机上运行了该脚本，唯一遇到此错误的系统就是我的系统。该脚本已编写为自动执行下载过程。我陷入了困境。请帮忙！

我用来运行脚本的命令：xargs -I ds ./exportfile.csh ds [email protected] <pt

csh 脚本：

#! /bin/csh -f
#
# Updated 27 July 2015 to deal with changes for more compact json output format.
#         also added tests for wget failures
# updated 20 March 2015 to deal with new need to not urlescape to words on left of '='
#
# Simple script to fetch a JSOC recordset using calls to wget
#
# call with a two arguments containing a recordset query and your registered email address
# resulting data files are placed into the current directory
#
# see http://jsoc.stanford.edu/jsocwiki/AjaxConnect for further information
#
# e.g.
#   exportfile.csh 'hmi.M_45s[$]' [email protected]
# will get you the most recent SDO/HMI line-of-sight magnetogram if you replace the [email protected] with your
# registered email address (see below)

set noglob

if ($#argv != 2) then
  Two args required, recset and notify
  call=$argv
  exit
endif

# get desired recordset and encode for transmitting
# you can get the following url_escape script at http://jsoc.stanford.edu/ajax/

set ds=`./url_escape.pl "$1"`

# You MUST now include a valid registered email address.  You can use a prior exportdata "notify" email address
# or just make one via http://jsoc2.stanford.edu/ajax/register_email.html
# Change the '$2' in the line below to your notify address if you want the script to not need a second argument.

set notify = `./url_escape.pl "$2"`

# for FITS without full headers use fastest method use the next 2 lines:

# set method=url_quick
# set protocol=as-is

# if, as is most common, you want full FITS headers or
# if you want to specify the filename format for the returned data or if you expect multiple
# files you should use the next two lines.

set method=url
set protocol="FITS"

# to specify filename formats add the "filenamefmt" command to the cmd line below.
# you will need to url_escape the filenamefmt.

# The cgi-bin programs that you can use with wget or curl or such programs include
#   jsoc_fetch
#   jsoc_info
#   show_series
#   show_info
#
#   If you need to pass flags (e.g. -X) to these programs, use 'X=1' on the urlencoded command line.
#   To see the full set of options see the man pages in doxygen from the jsoc2 home page.
#
# If you want to run exportfile.csh to fetch a group of recordsets you can place them
# into a file, one line per recordset, with surrounding single quotes, and no internal spaces.
# then use xargs to bring the set of recordsets, one at a time.

答案1

我运行了脚本，-v结果发现问题出在变量上$?。
