I can't seem to work out what the issue with the following if statement is in regards to the elif and then. Keep in mind the printf is still under development I just haven't been able to test it yet in the statement so is more than likely wrong.
The error I'm getting is:
./timezone_string.sh: line 14: syntax error near unexpected token `then' ./timezone_string.sh: line 14: `then' And the statement is like so.
if [ "$seconds" -eq 0 ];then $timezone_string="Z" elif[ "$seconds" -gt 0 ] then $timezone_string=`printf "%02d:%02d" $seconds/3600 ($seconds/60)%60` else echo "Unknown parameter" fi 5 Answers
There is a space missing between elif and [:
elif[ "$seconds" -gt 0 ] should be
elif [ "$seconds" -gt 0 ] All together, the syntax to follow is:
if [ conditions ]; then # Things elif [ other_conditions ]; then # Other things else # In case none of the above occurs fi As I see this question is getting a lot of views, it is important to indicate that the syntax to follow is:
if [ conditions ] # ^ ^ ^ meaning that spaces are needed around the brackets. Otherwise, it won't work. This is because [ itself is a command.
The reason why you are not seeing something like elif[: command not found (or similar) is that after seeing if and then, the shell is looking for either elif, else, or fi. However it finds another then (after the mis-formatted elif[). Only after having parsed the statement it would be executed (and an error message like elif[: command not found would be output).
You have some syntax issues with your script. Here is a fixed version:
#!/bin/bash if [ "$seconds" -eq 0 ]; then timezone_string="Z" elif [ "$seconds" -gt 0 ]; then timezone_string=$(printf "%02d:%02d" $((seconds/3600)) $(((seconds / 60) % 60))) else echo "Unknown parameter" fi [ is a command (or a builtin in some shells). It must be separated by whitespace from the preceding statement:
elif [ I would recommend you having a look at the basics of conditioning in bash.
The symbol "[" is a command and must have a whitespace prior to it. If you don't give whitespace after your elif, the system interprets elif[ as a a particular command which is definitely not what you'd want at this time.
Usage:
elif(A COMPULSORY WHITESPACE WITHOUT PARENTHESIS)[(A WHITE SPACE WITHOUT PARENTHESIS)conditions(A WHITESPACE WITHOUT PARENTHESIS)] In short, edit your code segment to:
elif [ "$seconds" -gt 0 ] You'd be fine with no compilation errors. Your final code segment should look like this:
#!/bin/sh if [ "$seconds" -eq 0 ];then $timezone_string="Z" elif [ "$seconds" -gt 0 ] then $timezone_string=`printf "%02d:%02d" $seconds/3600 ($seconds/60)%60` else echo "Unknown parameter" fi Missing space between elif and [ rest your program is correct. you need to correct it an check it out. here is fixed program:
#!/bin/bash if [ "$seconds" -eq 0 ]; then timezone_string="Z" elif [ "$seconds" -gt 0 ]; then timezone_string=$(printf "%02d:%02d" $((seconds/3600)) $(((seconds / 60) % 60))) else echo "Unknown parameter" fi useful link related to this bash if else statement
