I need to read a file line by line. Every line read needs to be stored in a variable which will be further tokensied into words using \ , : as the seperators.

Can you please provide such script?

The code may have worked with you cause you might not have used a file which has "\" "/" ":" as the characters in every line read. Can you help in this scenario?

./script.sh works finr

but sh script.sh gives following error


Code:
': not a valid identifier_KEYS.sh: line 2: read: `line

The error posted usually occurs when the script file is in MSDOS text format not unix text format. Was the file edited using a Microsoft Windows editor like "notepad"?

In case it's relevant, that read will discard leading and trailing IFS whitespace, will join lines if the previous line ends with a backslash, and swallow all other backslashes. If you want to faithfully reproduce the lines in the file using read, the following is the way to do it:
Code:
while IFS= read -r line; do ....
