如何使用Sed命令将文件精确地附加在最后一句的末尾

Question

I need to output a bash scripts in csv format, the output i wanted is as follow. while i need to append file named 1.2.6.2.txt right after the tail of 1.2.6.1.txt and it cannot be a next row entry, preferred to finish this using sed command.

#cat result/1.2.6.1.txt
1.2.6 Disable Proxy Modules,command to get result httpd -M | grep proxy_,expected result should be null

And:

#cat result/1.2.6.2.txt
" proxy_module (shared)
 proxy_ajp_module (shared)
 proxy_balancer_module (shared)
 proxy_connect_module (shared)
 proxy_express_module (shared)
 proxy_fcgi_module (shared)
 proxy_fdpass_module (shared)
 proxy_ftp_module (shared)
 proxy_http_module (shared)
 proxy_scgi_module (shared)
 proxy_wstunnel_module (shared)"

The output i needed:

1.2.6 Disable Proxy Modules,command to get result httpd -M | grep proxy_,expected result should be null,"
proxy_module (shared)
proxy_ajp_module (shared)
proxy_balancer_module (shared)
proxy_connect_module (shared)
proxy_express_module (shared)
proxy_fcgi_module (shared)
proxy_fdpass_module (shared)
proxy_ftp_module (shared)
proxy_http_module (shared)
proxy_scgi_module (shared)
proxy_wstunnel_module (shared)
"

Already tried this command to able to append text right after the tail of a file

sed -e $'$s/$/:SUFFIX &/' result/1.2.6.1.txt

1.2.6 Disable Proxy Modules command to get result httpd -M | grep proxy_ expected result should be null:SUFFIX

But when i tried the command below, the e cat result/1.2.6.2 command which suppose to add the content of 1.2.6.2.txt after the original sentence doesn't work:

# sed -e $'$s/$/{e cat result\/1.2.6.2.txt}/' result/1.2.6.1.txt
1.2.6 Disable Proxy Modules
command to get result httpd -M | grep proxy_
expected result should be null{e cat result/1.2.6.2.txt}

Answer 1

You are getting that error because you need to escape the / character in {e cat result/1.2.6.2.txt} . So you could run it as follows:

sed -e $'s/$/{e cat result\/1.2.6.2.txt}/' result/1.2.6.1.txt

Without using sed , you can simply run:

var1=$(cat result/1.2.6.1.txt)
var2=$(cat result/1.2.6.2.txt)
echo $var1$var2 >result/final.txt
