note 126011 added to ref.exec

Using Linux Ubuntu 16.04 apache2 php 7 on Lenovo laptop 32 bit. Exec command worked only after I closed terminal. I have tried the following command: $output = exec( "php script.php | awk -F= '{printf \"%d %s\n\", length($1), $0}' glossary2.snpz | sort -rn -k1,1 | sed -E -e 's/^[0-9]+ // ' " ) ; echo $output; I hope it will be useful to others. Context: I have used the output as a string for my php script to design a Translation Script from English to Telugu. ---- Server IP: 45.112.84.4 Probable Submitter: 45.112.85.242 (proxied: 117.249.172.43) ---- Manual Page -- https://php.net/manual/en/ref.exec.php Edit -- https://main.php.net/note/edit/126011 Del: integrated -- https://main.php.net/note/delete/126011/integrated Del: useless -- https://main.php.net/note/delete/126011/useless Del: bad code -- https://main.php.net/note/delete/126011/bad+code Del: spam -- https://main.php.net/note/delete/126011/spam Del: non-english -- https://main.php.net/note/delete/126011/non-english Del: in docs -- https://main.php.net/note/delete/126011/in+docs Del: other reasons-- https://main.php.net/note/delete/126011 Reject -- https://main.php.net/note/reject/126011 Search -- https://main.php.net/manage/user-notes.php
