Test the download degree with Shell under Linux. The code is as follows:
The code is as follows:
#! / bin/bash
# date:20140210
# used for test server download speed
Ritual host = "188.18.28.19"
Ringing dirt = "/ home/test0208/tmp"
Ringing file = "$r_dir/ddfile2m"
Lumped dirt = "/ home/yangjuying/tmp"
Lumped file = "$l_dir/ddfile2m"
Lumped log = "$l_dir/182.18.28.19-download.log"
Echo "- $(date +% Y%m%d-%H%M%S) -" > > $l_log
Start_t= "$(date + s)"
Scp-P22-o connecttimeout=10-o GSSAPIAuthentication=no test0208@$r_host:$r_file $l_file > > $l_log 2 > & 1
Rc= "$?"
If ["$rc"-eq 0]; then
Stop_t= "$(date + s)"
File_stat= "$(stat $l_file)"
File_ctime= "$(echo" $file_stat "| awk-F" [.] "'FNR==5 {print $2 camera 3}' | sed's / [-:] / / g')"
File_ct= "$(awk-v t =" $file_ctime "'BEGIN {print mktime (t)}')"
File_size= "$(du-sm $l_file | cut-F1)"
Rm "$l_file"
Else
Stop_t= ""
Fi
If [- n "$stop_t"]; then
Connect_t=$ (($file_ct-$start_t))
Transfer_t=$ (($stop_t-$file_ct))
All_t=$ (($stop_t-$start_t))
Speed= "$(echo" scale=3;$file_size/$transfer_t "| bc)"
