Dear Folks,
I am having a requirement to grep a word which could be a part of a substring of a file. Please help me with the command for korn shell.
Let me give you a example
I am having a file in which the data is based on positions.
Lets say
1-5 is Emp ID 6-10 is Emp Name 11-15 is Salary
Now my requirement is when I search for Emp Id 10110 in the file using grep command It shud NOT return me the third and fourth lines. Because those two lines salary value is same as the value of Emp Id of first line.
Please help me with this. It is a urgent requirement for me.
This is probably pretty simple butI'm not sure how to best go about it.
If I have
FILE="myBigLongFileName_1.xls"
FILE_PREFIX=`echo $FILE| cut -d"." -f1`
# that gives "myBigLongFileName_1"
All i want to do now is chop the "_1" from the end of $FILE_PREFIX
Any ideas anyone? (3 Replies)

grep
GREP(1) General Commands Manual GREP(1)NAME
grep - search a file for lines containing a given pattern
SYNOPSIS
grep [-elnsv] pattern [file] ...
OPTIONS -e-e pattern is the same as pattern
-c Print a count of lines matched
-i Ignore case
-l Print file names, no lines
-n Print line numbers
-s Status only, no printed output
-v Select lines that do not match
EXAMPLES
grep mouse file # Find lines in file containing mouse
grep [0-9] file # Print lines containing a digit
DESCRIPTION
Grep searches one or more files (by default, stdin) and selects out all the lines that match the pattern. All the regular expressions
accepted by ed and mined are allowed. In addition, + can be used instead of * to mean 1 or more occurrences, ? can be used to mean 0 or 1
occurrences, and | can be used between two regular expressions to mean either one of them. Parentheses can be used for grouping. If a
match is found, exit status 0 is returned. If no match is found, exit status 1 is returned. If an error is detected, exit status 2 is
returned.
