I am writing a script which will read a word and say how many vowels and consonants does the word contain. but i dont know how to traverse a string in shell scripting. if it was in C i'd have done something like this:
Code:
cout<<"plz enter the word"<<endl;
cin>>word;
int consonants, vowels;
for(int i=0;i<word.size();i++)
{
if(word[i] is a consonant)
consonants ++;
else
vowels++;
}
but i have no idea how to use for loop like that in shell.
thanks in advance

Hi Folks
I am pretty new to unix and shellscripting.
I need help on writing logic on traversing recursively through a set of directories under a top-level folder and delete files(mostly text) which are 1 month old.
Can you people help me on this?
Thanks a lot

Hello,
I want to loop thru a vector composed of many entries as structure, which contains sequenceID and sequence. At looping, delete any structure if the sequence is a perfect-match substring of another sequence of any other structure, so that the resulted vector contains only unique sequences.... (1 Reply)

exit
exit(1) User Commands exit(1)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.
