Top Forums Shell Programming and Scripting How to check file name format using shell script? Post 302460615 by umar.shaikh on Thursday 7th of October 2010 06:53:14 AM

I can think of a quick way to do this via 'cut'.
The first part would be to get rid of the file extension:
Code:
FILE_SHORT_NAME=`echo $FILE_NAME | cut -d'.' -f1`

The next would be to split the remaining name into 5 parts and check if each part is present:

Code:
PART_1=`echo $FILE_SHORT_NAME | cut -d'_' -f1`
PART_2=`echo $FILE_SHORT_NAME | cut -d'_' -f2`
PART_3=`echo $FILE_SHORT_NAME | cut -d'_' -f3`
PART_4=`echo $FILE_SHORT_NAME | cut -d'_' -f4`
PART_5=`echo $FILE_SHORT_NAME | cut -d'_' -f5`

You could then do basic checks to make sure that none of these parts is an empty string:

Code:
if [ -z $PART_1 ]
then
        echo "Please enter a correct filename"
fi

And similarly for the other parts as well. Up to you whether you want to get them in bulk and check them or get them one by one and check them and throw an error at the first place itself!

NAME
exit, return, goto - shell built-in functions to enable the execution of the shell to advance beyond its sequence of steps SYNOPSIS
sh exit [n] return [n] csh exit [ ( expr )] goto label ksh *exit [n] *return [n] DESCRIPTION
sh exit will cause the calling shell or shell script to exit with the exit status specified by n. If n is omitted the exit status is that of the last command executed (an EOF will also cause the shell to exit.) return causes a function to exit with the return value specified by n. If n is omitted, the return status is that of the last command exe- cuted. csh exit will cause the calling shell or shell script to exit, either with the value of the status variable or with the value specified by the expression expr. The goto built-in uses a specified label as a search string amongst commands. The shell rewinds its input as much as possible and searches for a line of the form label: possibly preceded by space or tab characters. Execution continues after the indicated line. It is an error to jump to a label that occurs between a while or for built-in command and its corresponding end. ksh exit will cause the calling shell or shell script to exit with the exit status specified by n. The value will be the least significant 8 bits of the specified status. If n is omitted then the exit status is that of the last command executed. When exit occurs when executing a trap, the last command refers to the command that executed before the trap was invoked. An end-of-file will also cause the shell to exit except for a shell which has the ignoreeof option (See set below) turned on. return causes a shell function or '.' script to return to the invoking script with the return status specified by n. The value will be the least significant 8 bits of the specified status. If n is omitted then the return status is that of the last command executed. If return is invoked while not in a function or a '.' script, then it is the same as an exit. On this man page, ksh(1) commands that are preceded by one or two * (asterisks) are treated specially in the following ways: 1. Variable assignment lists preceding the command remain in effect when the command completes. 2. I/O redirections are processed after variable assignments. 3. Errors cause a script that contains them to abort. 4. Words, following a command preceded by ** that are in the format of a variable assignment, are expanded with the same rules as a vari- able assignment. This means that tilde substitution is performed after the = sign and word splitting and file name generation are not performed. ATTRIBUTES
