perl - Error fg no job control - 


set /p input=options: [r]ead, [w]rite, [m]ixed:  if "%input%"=="w"   perl ftl_log_read.pl random_read.txt > random_read.dat fi  if "%input%"=="r"    perl ftl_log_write.pl random_write.txt > random_write.dat fi  if "%input%"=="m"    perl ftl_log_read.pl random_rw.txt > random_read.dat    perl ftl_log_write.pl random_rw.txt > random_write.dat fi

while compiling in linux machine getting "line 3: fg: no job control"

this run.bat file

please me resolve issue

it seems executing windows batch file (.bat) bash shell script. these have incompatible syntax. you need rewrite run.bat script shell script if want run under linux.

background:

the bash if statement expects command condition, not comparison expression. "%input%"=="w" undergo variable expansion, invoked command. string comparison written if [[ "$input" = "w" ]]; ...; fi. note shell variables $name whereas batch variables %name%.

bash features job control. shell can juggle multiple background processes. if run command %foo expand name of background command beginning foo, bring command foreground.

however, job control available in interactive sessions, i.e. if use bash interactive command line, not script interpreter. bash therefore reports error message “no job control” , terminates.

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
