I'm trying to remove the first / from a string in a shell script.
For example
file:///path/to/file
and output to
file://path/to/file

If the string is in a shell variable, then you can use shell parameter expansion:
$ var='file:///path/to/file'
$ echo "${var/\//}"
file://path/to/file

1IMHO this is the true answer, as it doesn't rely on calls to other programs to answer the OP's question. Nicely done.bgregs– bgregs2018-11-09 21:50:34 +00:00Commented Nov 9, 2018 at 21:50
Something like will do the work:
A="file:///path/to/file"
B=$(echo $A|sed 's@/@@')
without g at the end in sed the program will change only first occurrence
I Tried with below method and it worked fine
@praveen_linux_example ~]# echo "file:///path/to/file" | sed "s/\///1"
file://path/to/file
Command: echo "file:///path/to/file" | sed "s/\///1"
Output
file://path/to/file
