Top Forums Shell Programming and Scripting shell script to print words having first and last character same. Post 302516254 by 2pugs on Friday 22nd of April 2011 09:36:35 AM

Are you trying to match the first and last character of each line? If so I fixed a few syntax errors you had and so I believe this should work for you now.

Code:
#!/bin/ksh
 
if [ $# -ne 1 ]
then
    echo "Please enter a filename as argument"
    exit 1
fi

cat $1 | while read TEXT
do
    LEN=${#TEXT}
    # Removed '#' because we want to compare the character
    #   not the length of the text
    firstchar=`echo ${TEXT} | cut -c 1`
    lastchar=`echo ${TEXT} | rev | cut -c 1`
 
    # Fixed the syntax for 'if' statement and changed 'eq' to '='
    if [ "$firstchar" = "$lastchar" ]
    then
        echo ${#TEXT}
    fi
done

Enjoy.

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
