Hi,
I am writing a BASH script. I have a list of files and I would like to make sure that each is of a specific pattern (ie *.L2). If not I would like to remove that file. How do I test whether a filename matches a given pattern?
Thanks a lot.

Hi All,
I'm new to unix shell scripting.. Could someone guide me.
I have to search a string in the entire directory, once the search string is matched, it should print the line number of the string that matches and also the line and along with
it, it should print the file name.
Thanks,... (5 Replies)

Hi
I would like to extract the first portion of filename from a list of files.
The filename pattern is of the form 123456789_TEXT_TEXT_TEXT_.csv. I want to extract just the numerical portion of this filename from the list of files and then output this into another text file.

test - condition evaluation command
SYNOPSIS
test expression
expression
DESCRIPTION
test evaluates the expression expression and if its value is true, sets a 0 (TRUE) exit status; otherwise, a non-zero (FALSE) exit status
is set; test also sets a non-zero exit status if there are no arguments. When permissions are tested, the effective user ID of the process
is used.
All operators, flags, and brackets (brackets used as shown in the second SYNOPSIS line) must be separate arguments to test. Normally these
items are separated by spaces.
USAGE
Primitives
The following primitives are used to construct expression:
-r filename True if filename exists and is readable.
-w filename True if filename exists and is writable.
-x filename True if filename exists and is executable.
-f filename True if filename exists and is a regular file.
-d filename True if filename exists and is a directory.
-c filename True if filename exists and is a character special file.
-b filename True if filename exists and is a block special file.
-p filename True if filename exists and is a named pipe (FIFO).
-u filename True if filename exists and its set-user-ID bit is set.
-g filename True if filename exists and its set-group-ID bit is set.
-k filename True if filename exists and its sticky bit is set.
-s filename True if filename exists and has a size greater than 0.
-t[fildes] True if the open file whose file descriptor number is fildes (1 by default) is associated with a terminal device.
-z s1 True if the length of string s1 is 0.
-n s1 True if the length of the string s1 is non-zero.
s1 = s2 True if strings s1 and s2 are identical.
s1 != s2 True if strings s1 and s2 are not identical.
s1 True if s1 is not the null string.
n1 -eq n2 True if the integers n1 and n2 are algebraically equal. Any of the comparisons -ne, -gt, -ge, -lt, and -le may be used in
place of -eq.
Operators
These primaries may be combined with the following operators:
! Unary negation operator.
-a Binary and operator.
-o Binary or operator (-a has higher precedence than -o).
`(expression)` Parentheses for grouping. Notice also that parentheses are meaningful to the shell and, therefore, must be quoted.

| ATTRIBUTE TYPE | ATTRIBUTE VALUE |

SEE ALSO find(1), sh(1), attributes(5)NOTES
If you test a file you own (the -r , -w , or -x tests), but the permission tested does not have the owner bit set, a non-zero (false) exit
status will be returned even though the file may have the group or other bit set for that permission. The correct exit status will be set
if you are super-user.
The = and != operators have a higher precedence than the -r through -n operators, and = and != always expect arguments; therefore, = and !=
cannot be used with the -r through -n operators.
If more than one argument follows the -r through -n operators, only the first argument is examined; the others are ignored, unless a -a or
a -o is the second argument.
