I am writing some script to make a directory, but I want firstly sure that the name that the user insert is correct. for this issue I wrote something like below (FILE.txt is the file which the user name saved in)
if grep -q '>' FILE.txt then echo "You should avoid inserting ">" in your code!" fi But it seems that the bash thought that I want to insert to output and so it give this error: -sh: syntax error near unexpected token `newline' Do anybody have some idea? tnx for help
The problem isn't with your grep line, it's with your echo line. Your shell sees it as:
echo "You should avoid inserting " > " in your code!" You can fix this simply by removing the quotes in the middle of the sentence, or using single quotes like:
echo "You should avoid inserting '>' in your code!" 
"" around > like this: echo You should avoid inserting '">"' in your code!You have to escape the quote in your echo statement:
if grep -q '>' file.txt; then echo "You should avoid inserting \">\" in your code!" else echo "code is good" fi
