i'm trying concatenate files 1.txt , 2.txt, , several html files. i'm trying save them .php after concatenation after. i've tried follows, doesn't work. step 1: sudo find . -name "*.html" -type f -exec ./code.sh {} \; code.sh cat 1.txt $1 2.txt > mv $1 `echo $1 | sed 's/\.html/.php/'`; any ideas how solve this? your problem you're trying write file called mv along other parameters. i think mean code.sh is: cat 1.txt $1 2.txt > $(echo $1 | sed 's/\.html/.php/')

i have c# application want connect sql server , server , application used on same machine , application cannot connect sql if installed application on machine , keeping server in first server connected ! server installed on windows 8. thanks please following - make sure local database server has both windows authentication , sql server authentication mode enabled. but if using windows authentication change connection string - connectionstring="data source=lenovo;initial catalog=app;integrated security=true;" if using sql server authentication mode, seems since providing username connectionstring="data source=lenovo;initial catalog=app;integrated security=false;user id=sa;password=111" also, app reserve keyword in systems. better avoid such name name of db. if using default server instance can use . or (local) instead of lenovo

i have heard term dirty read many times in beginning career of development. somehow understand want expert's light on it. does diminish performance issues ? or making wrong assumptions. please provide characteristic also. thanks in advance. quite in database processing, come across situation wherein 1 transaction can change value, , second transaction can read value before original change has been committed or rolled back. known dirty read scenario because there possibility first transaction may rollback change, resulting in second transaction having read invalid value. while can command database disallow dirty reads, degrades performance of application due increased locking overhead. disallowing dirty reads leads decreased system concurrency.

i have class may need large, unchanging, data-structure based on contents of enum class. what i'm interested know whether better me initialise in static block, or should initialise within method accesses data (in case it's never used)? here's example: public enum myenum { foo ("foo"), bar ("bar"), foobar ("foo_bar"); private final string othername; private myenum (string othername) { this.othername = othername; } private static final map<string, myenum> othernames = new hashmap<string, myenum>(); } now, have 2 options initialising othernames map, first being use static block so: static { (myenum entry : myenum.values()) othernames.put(entry.othername, entry); } public static myenum valuebyothername (string othername) { return othernamesstatic.get(othername); } or alternatively can initialise map first time lookup requested like-so: public static myenum valu...
