顶部输出在 cron 中缩小

dai*_*cub 4 email bash curses

我正在尝试通过 cron 发送电子邮件以了解哪些进程占用了我的服务器。它工作正常,但生成的电子邮件太窄,我需要了解更多有关该过程的信息。

这是我正在使用的脚本(从这里偷来的:http : //www.inmotionhosting.com/support/website/server-usage/create-server-load-monitoring-bash-script):

#!/bin/bash
trigger=10.00
load=`cat /proc/loadavg | awk '{print $1}'`
response=`echo | awk -v T=$trigger -v L=$load 'BEGIN{if ( L > T){ print "greater"}}'`

if [[ $response = "greater" ]]
then
top -cSbn 1 | head -14 | tail -8 | mail -s"High load on server - [ $load ]" myemail@domain.com
fi

生成的电子邮件类似于:

如您所见,缺少整个路径。但是如果我从 bash 运行脚本,它就可以工作,发送足够宽的电子邮件。

这是 ncurses 问题吗?管道邮件问题?

谢谢!

使用-w开关top

   -w  :Output-width-override as:  -w [ number ]
        In  'Batch'  mode,  when  used without an argument top
        will format output using the COLUMNS= and LINES= envi?
        ronment  variables,  if set.  Otherwise, width will be
        fixed at the maximum 512 columns.  With  an  argument,
        output width can be decreased or increased (up to 512)
        but the number of rows is considered unlimited.

        In normal display mode, when used without an  argument
        top  will  attempt to format output using the COLUMNS=
        and LINES= environment variables,  if  set.   With  an
        argument,  output  width  can  only  be decreased, not
        increased.  Whether using environment variables or  an
        argument with -w, when not in 'Batch' mode actual ter?
        minal dimensions can never be exceeded.

        Note: Without the use  of  this  command-line  option,
        output  width is always based on the terminal at which
        top was invoked whether or not in 'Batch' mode.
