问题 I need to print the following: need smart ways by printf to print this example param1 ............... value1 param2 ............... value2 param3 ............... value1 param4 ............... value2 THX 回答1: for i in 1 2 3 4 do printf "param%d ................. value%d\n" $i $i done 回答2: This works in ksh93.

问题 I have a Korn shell script that is supposed to zip up files and it is not working properly in development. The same exact script works in production which is strange. We recently upgraded our Solaris Unix box to a Linux box in the development environment. So I am assuming that this may be the cause of the script not executing. The pic below is shows the file list. The user will select a checkbox for the files they want to download and then they click the zip and download link and it should

问题 I have a code if ["a1 a2" = "a*"] then echo match else echo "a*" fi that I have typed and the return statement is a* main.ksh[3]: [a1 a2: not found [No such file or directory] I am wondering why this is, I thought the if statement only compared the strings. What does it have to do with files and directories? 回答1: Spacing issue, you need to do if [ "a1 a2" = "a*" ] otherwise at least "a1 will get treated as part of the test operator. Also to do regex matching, you need to do something like if

问题 Do shells such as bash and ksh support set operations (such as 'union of two sets')? I can't find any tutorial about this using Google. 回答1: What about this set-operations-in-unix-shell. 回答2: As far as I know, POSIX shell (including bash) doesn't support sets operation. But you can build your own, for example, by making use of bash associative array (bash 4.0 and later). 回答3: No bash/ksh doesn't support dedicated sets operations. You will have to program your own if you insists on using the

问题 I've the following 5 second timer which prints an asterisk for each second. timer () { i=1 trap 'i=5' INT while [[ $i -le 5 ]]; do sleep 1 printf "*" ((i+=1)) done } Somehow the trap chunk seems a little hackish and I wonder if there's a more correct way to interrupt the entire loop (not just the current sleep cycle). I've tried: trap 'print "foo"' INT at various locations inside and outside the function, but as I alluded to before, that just interrupts the current sleep cycle. 回答1: Perhaps I

问题 I'm trying to get last executed command from command line from a script to be saved for a later reference: Example: # echo "Hello World!!!" > Hello World!!! # my_script.sh > echo "Hello World!!!" and the content of the script would be : #!/usr/bin/ksh fc -nl -1 | sed -n 1p Now as you notices using here ksh and fc is a built in command which if understood correctly should be implemented by any POSIX compatible shells. [I understand that this feature is interactive and that calling same fc

问题 I have created a script that formats all of my PL/SQL files into a simple file that has pairs of values, its quite hard to explain, i think it will be easier if you just look at the file; PROCEDURE VALIDA_CAMBIO_GPR TRUNCATE TMP_MOD_PVA INSERT TMP_MOD_PVA PROCEDURE AJUSTAR_FECHAS INSERT PRO_TDA_VARLOG_ALM PROCEDURE DEPURAR_CAMBIOS_GPR PROCEDURE INC_EX_0001 INSERT CABECERA_ALARMAS PROCEDURE INC_EX_0002 INSERT CABECERA_ALARMAS PROCEDURE INC_EX_0003 INSERT CABECERA_ALARMAS PROCEDURE INC_EX_0005
